A clock adder adds the reconstructing clock frequency f1 to the first clock frequency error, resulting in a synthesized clock frequency f2. The receiver clocks a second wired data connection, using the synthesized clock frequency f2.
Data transfer system
A data transfer system which can surely transfer data between two function circuits which operate synchronously with different clock frequencies. A data loading signal is generated just before timing when edges of two clocks of different frequencies coincide. Only information data received by the function circuit on a transfer data reception side within an existence period of the data loading signal is determined to be valid.

Techniques for performing joint detection with a common midamble for downlink transmission are described. In one design, a user equipment (UE) may obtain samples for a burst transmitted by a Node B on the downlink. The burst may include at least one data field and a common midamble. The UE may derive a channel impulse response estimate for each of multiple orthogonal codes based on (i) a channel impulse response estimate derived based on samples for the common midamble and (ii) a traffic-to-pilot ratio (T2P) estimated for that orthogonal code based on the samples for burst. The UE may perform joint detection, for the multiple orthogonal codes, on samples for the at least one data field based on the multiple channel impulse response estimates.
Adaptive OFDM receiver based on carrier frequency offset
An adaptive receiver comprises a receiver module that receives an orthogonal frequency division multiplexing (OFDM) signal. An operating parameters module monitors at least one operating parameter of the receiver module and generates a select signal based the at least one operating parameter. An estimator module selects between first and second algorithms based on the select signal and selectively estimates a carrier frequency offset (CFO) of the OFDM signal using the one of the first and second algorithms. Alternately, an estimator module adjusts algorithm operating parameters of a first algorithm based on the select signal and selectively estimates a carrier frequency offset (CFO) of the OFDM signal using the selected algorithm operating parameters of the first algorithm.

Time-dependent trellis coding for more robust digital television signals
Different sets symbols are precluded at prescribed times in time-dependent trellis coding. This increases the distances between different individual symbols as well as the distances between trellis codes, which increases the robustness of data transmission. The symbols that are precluded in this time-dependent trellis coding are determined in advance according to a prescribed pattern, which pattern does not depend on the history of previous symbols. The Viterbi decoder used for trellis decoding in a receiver can be designed to take advantage of knowledge concerning which different sets of symbols are precluded at prescribed times.

Radio wave generator, wireless communication system, radio interference prevention control method, and radio interference prevention control program
The present invention is to provide a wireless communication system that is capable of preventing occurrence of radio interference caused by radio wave used by a radio wave generator without requiring any improvement of existing wireless devices. The wireless communication system of the present invention includes: a radio wave generator (1) that uses at least a radio wave in a frequency band that overlaps a frequency band used by a wireless standard; and wireless devices (AP, STA) each of which uses a radio wave conforming to the wireless standard. The radio wave generator (1) transmits a dummy frame conforming to the wireless standard to the wireless devices near the radio wave generator (1) before generating the radio wave in the same frequency band as the frequency band used by the wireless standard. When the wireless devices (AP, STA) receive the dummy frame, the wireless devices (AP, STA) control themselves to stop using the radio wave in the frequency band that has radio interference caused by the radio wave generated from the radio wave generator (1).
