Receiving apparatus and signal processing method
In the reception and demodulation of a communication signal with frequency hopping among a plurality of frequency bands, a demodulator is formed by a balance circuit. The demodulator performs frequency conversion by multiplying signals in_a and in_b, which are obtained by converting a received signal into differential signals, by local signals Lo—1a and Lo—1b with a frequency corresponding to a frequency band of the received signal, which are frequency-switched during a guard interval period of the received signal, in synchronization with a symbol of the received signal. Further, two output ends of the demodulator are charged/discharged through capacitors in synchronization with frequency switching of the local signal so that a voltage difference between the two output ends of the demodulator becomes a prescribed level. |

Autonomous wireless networks
A device is operable to use received signals to divide time into a succession of frames, each frame having plural consecutive timeslots, and into a succession of four or more superframes. A transmitter is operated only in a single timeslot in one frame.

The device determines which timeslots of the first frame are occupied to provide local awareness information, and transmits it as a code on its transmit timeslot along with payload data. This allows other devices in a network to obtain information about their local environment and about the environment of their neighbors. Routing decisions are made on this basis. |

System for data transfer in a wireless network
A wireless network protocol employs a hop-by-hop block formation approach in which data packets are organized into data blocks at each hop according to a routing table and are transmitted to each hop as data blocks. For example, data packets to be transmitted from a source node to a destination are grouped into a data block associated with a routing table. The source node transmits the data packets according to the routing table. Each node in the routing table determines which data packets it must transmit to other nodes to complete transmission of the data packets to the destination. Each such node determines a new routing table and groups these data packets into a new data block associated with the new routing table. Each node transmits the data packets of the new data block according to the new routing table in a manner similar to the source node. |

The invention relates to enabling differential forwarding in address-based carrier networks such as Ethernet networks. There is described a method of and connection controller for establishing connections (76, 77) in a frame-based communications network comprising nodes (71-75 and 78) such as Ethernet switches.

By using the combination of destination (or source) address AND identifier, the mappings enable data frames belonging to different connections (76, 77) to be forwarded differentially (ie forwarded on different output ports) at a node (75) despite the different connections having the same destination node. This enables flexibility in routing connections and the ability to perform traffic engineering. |

Virtual dial-up protocol for network communication
A layer two forwarding protocol (L2F) provides virtual direct dial-up service into private networks through public internet service providers. An authorized remote client appears as a direct dial-up client to the home gateway, even through the client is accessing the home gateway remotely through the ISP. The new forwarding protocol allows the remote client to conduct point-to-point link protocols, such as point-to-point protocol (PPP) and serial line interface protocol (SLIP) directly with the local network home gateway. The network access server changes from a routing mode where a communication protocol is conducted with the client to a switching mode where the POP simply sends data from one port to a tunnel. The tunnel then transmits the data to another port, regardless of the header information on transmitted data packets. The remote client can then be managed through databases controlled by the local network and gain access to resources not typically accessible through the internet. The layer two forwarding protocol conducts an independent authorization session to prevent unauthorized access to the private network and provides point-to-point protocol transport over the internet independently of internet transport protocols. |

Latency-aware adaptive bandwidth request mechanism for real-time communication in WiMAX
A method and apparatus for requesting bandwidth in a subscriber station is disclosed. The method dynamically changes the size of the bandwidth request based on the prediction of the number of packets needed to be transmitted. The average delay experienced by packets in a queue is measured, and this information is then used to change the coefficient of a prediction equation. When the experienced average delay is below the agreed upon QoS latency parameter or delay target, the method reduces the size of the bandwidth requests by making the prediction equation more conservative. On the other hand, when the experienced delay is above the agreed upon latency, the algorithm will make the prediction equation more aggressive, increasing the bandwidth requests and reducing the latency for future packets. By modifying the prediction equation based on the measured delay, the method is able to select the optimal point for achieving time delay requirements while preserving air-link resources. |

Method and system to reduce stray light reflection error in time-of-flight sensor arrays
Haze-type phase shift error due to stray light reflections in a phase-type TOF system is reduced by providing a windowed opaque coating on the sensor array surface, the windows permitting optical energy to reach light sensitive regions of the pixels, and by reducing optical path stray reflection. Further haze-type error reduction is obtained by acquiring values for a plurality (but not necessarily all) of pixel sensors in the TOF system pixel sensor array. Next, a correction term for the value (differential or other) acquired for each pixel in the plurality of pixel sensors is computed and stored. Modeling response may be made dependent upon pixel (row, column) location within the sensor array. During actual TOF system runtime operation, detection data for each pixel, or pixel groups (super pixels) is corrected using the stored data. Good optical system design accounts for correction, enabling a simple correction model. |
