OFDM cellular communication method, system and base station
Since the OFDM communication method does not select whether plural sectors use a same terminal as a transmission destination, or always use it as a transmission destination, giving a preference to system throughput deteriorates channel quality of a terminal in a sector boundary, while increasing channel quality in sector boundaries greatly deteriorates system throughput. In a base station, when a sector transmits to a terminal in the front of a beam, only the sector performs the transmission, and when transmission is made to a terminal in a sector boundary off the direction of the beam, a different sector transmits to the same terminal using a same hopping pattern. Thereby, tradeoff between the channel quality of the terminal in a sector boundary and deterioration in system throughput can be minimized.

There is provided a mode-locked laser device including: a resonator; a solid-state laser medium that is disposed in the resonator and outputs oscillation light in accordance with the incidence of excitation light; a saturable absorber that is disposed in the resonator and induces soliton mode-locking; a group velocity dispersion correction component that is disposed in the resonator and controls group velocity dispersion in the resonator; and an excitation portion that causes excitation light to be incident at the solid-state laser medium, wherein a resonator length of the resonator is at least a resonator length with which soliton mode-locking is inducible and is less than a resonator length with which non-soliton mode-locking is inducible.
Pulsed light source
It is an object of the present invention to provide a compact and low-cost system for generating ultra short high energy laser light pulses that does not use the known CPA scheme. The proposed approach is based on spectral filtering of laser light pulses of a mode locked laser source. The used mode locked laser source can be of any kind as long as its filtered residual pulse bandwidth supports pulse durations longer than 20 ps and up to 1 ns. After filtering the laser light pulses are directly amplified in an amplification element consisting of one or more amplification stages. At the same time or just after amplification the light pulses are spectrally broadened through a spectral broadening element, for example a fiber of suitably chosen core diameter and length to achieve a spectral bandwidth that is wide enough to support sub 10 ps pulses. Finally, the spectrally broadened laser light pulses are compressed by a compact dispersive element consisting of one or more Bragg gratings or a grating pair.
Robust digital communication system
Normally ordered robust VSB data are reordered in accordance with a first interleave to produce reordered robust VSB data. The reordered robust VSB data and ATSC data are reordered in accordance with a second interleave to produce normally ordered robust VSB data and reordered ATSC data. The normally ordered robust VSB data and reordered ATSC data are time multiplexed for transmission to a receiver. The receiver discards the reordered ATSC data or the normally ordered robust VSB data depending upon receiver type or user selection. A robust VSB receiver is able to process the normally ordered robust VSB data upstream of an outer decoder without an interleave thereby avoiding the delay associated with an interleave.
Synchronized audio/video decoding for network devices
A method of synchronizing decoders within a network to a server includes receiving a set of timestamps and local clock signals upon receiving the beacon interrupt signal, computing differential timestamp and local clock values based on values of timestamp and local clock signals, respectively, within the sets of timestamp and local clock signals, determining whether the differential local clock value has a predetermined relationship with the differential timestamp value, and transmitting a clock rate adjustment command signal to the decoder when differential local clock value does not have the predetermined relationship with the differential timestamp value. The clock rate adjustment command signal adjusts the local system time clock of the decoder such that a subsequent differential clock value will have the predetermined relationship with the differential timestamp value. When this method is performed for each decoder within the network, the decoders are substantially synchronized and the decoding delay can be kept below humanly perceptible levels.
Method and apparatus for transmitting broadcasting information
In a method of transmitting broadcasting information, the broadcasting information is classified into fixed broadcasting information for transmitting to a fixed position of a super-frame and variable broadcasting information to be variably transmitted in the form of a broadcasting message. The fixed broadcasting information may be classified into primary broadcasting information having a short cycle and secondary broadcasting information having a long cycle.
Methods and apparatus for balancing modulation in cellular communications over noisy channels
Methods and apparatus for balancing multi-symbol modulation schemes in cellular communications are provided. The modulation schemes include a plurality of modulation symbols, each of which codes a predefined bit group, which includes one or more bits. The bit groups define different bit positions for bits within the bit groups. The bit positions of the modulation symbols are associated with different error probability levels. Each error probability level defines a probability level of an erroneous bit value at a defined bit position in the bit group, which is obtained by a mapping operation from the modulation symbol transmitted over a radio frequency channel with noise. Binary content to be modulated is provided in form of code blocks I (where i=1 to n). Each of the code blocks is carried on a corresponding code channel i. The code blocks on the code channels are supplied to the modulation schemes in that each code channel is associated with one predefined bit position of the bit groups to enable a mapping to modulation symbols. The bit groups are formed from the binary content of the code blocks in accordance with the code channel-to-bit position association defined above. The binary content of at least two code blocks is shuffled, distributed, or scattered in accordance with predetermined shuffling, distributing, or scattering rules. The shuffling, distributing, or scattering aims to achieve substantially balanced or same error probability levels for said code channels. The shuffling operation should be performed to achieve a substantially evenly distribution of the binary content upon the involved code blocks.
Method and system making it possible to manage erratic interruptions in a transmission system
Method and system are disclosed for managing erratic interruptions in a transmission system where the messages to be transmitted are composed of data packets and are expressed by means of a polynomial of degree t−1. The senders and the receivers share information making it possible to reference the data packets. In the course of the transmission of a message represented by a polynomial P, at least t points Ai are generated and P(Ai) of the polynomial P is evaluated, with t′ greater than or equal to t. The evaluations P(Ai) are transmitted of the t′ points to the receiver or receivers concerned, with information allowing the receivers to detect the transmission errors. Each receiver verifies that it has received t valid evaluations, that is to say free of transmission errors, uses the information referencing the packets and the t valid evaluations P(Ai) of the polynomial to determine the points Ai, and on the basis of the P(Ai) and of the Ai and determines the polynomial P used and on the basis of said polynomial deduces the message therefrom.
IP-USN with multiple and communication method
A router connects an Internet protocol (IP)-ubiquitous sensor network (USN) with an external network. The IP-USN is disclosed when the IP-USN includes one or more routers. An IP-USN with multiple routers includes one or more routers, and sensor nodes in the IP-USN may reliably communicate with the external network. The sensor nodes in the IP-USN may communicate with one another using the router if necessary. When one router does not operate, communication with the external network is performed by using other routers.
Method for determining a most probable K location
The process of traversing a K may involve determining a match between a root node and a Result node of a node on the asCase list of a current K node. When learning is off and a match is not found, the procedure may ignore the particle being processed. An alternative solution determines which node on the asCase list is the most likely to be the next node. While the K Engine is traversing and events are being recorded into a K structure, a count field may be added to each K node to contain a record of how many times each K path has been traversed. The count field may be updated according to the processes traversing the K. Typically, the count is incremented only for learning functions. This count field may be used in determining which node may be the most (or least) probable.
