Abstract: A coding section 101 performs error detection coding of data for each predetermined error detection unit, and an M-ary modulation section 102 arranges data belonging to a plurality of error detection units in one transmission unit, and transmits that data. A first decoding section 114 decodes a received signal, and performs error detection on the decoding result for each error detection unit. A second demodulation section 115 modifies the likelihood of each bit based on the result of error detection in the first decoding section 114. By this means, it is possible to improve the error correction capability of a signal that has undergone M-ary modulation using high-precision likelihoods, and to improve transmission quality.

Abstract: Of systematic bits (S) and parity bits (P1, P2) generated by coding (coding rate R=1/3) transmission bits, subcarriers to which parity bits are mapped are designated as candidates for transmission cancellation and subcarriers not to be transmitted are selected from among those candidates. When this selection is made, a selection pattern which corresponds to minimum peak power of an OFDM symbol is used based on values of parity bits and phase relationship between subcarriers.

Abstract: PL demodulation section 203 demodulates pilot signals of a received signal. SIR detection section 205 detects the reception quality of the demodulated pilot signals. fd detection section 206 detects a Doppler frequency using the demodulated pilot signals. Requested modulation method deciding section 207 decides a modulation method to be requested to the base station using the reception quality of pilot signals and the detected Doppler frequency. Command generation section 208 generates a command corresponding to the decided modulation method. Adaptive demodulation section 204 performs demodulation processing on the received signal using the demodulation method corresponding to the modulation method decided by requested modulation method deciding section 207. This makes it possible to maintain good reception quality even in a fading environment.

Abstract: Desired signal power detection sections 109 to 116 measure a signal power level from a communication partner received at respective antennas 101 to 108. Antenna set selection section 117 obtains a sum of signal power levels from the communication partner received at four antennas belonging to each of antenna sets A to D each composed of combined antennas selected in advance to form a predetermined radiation pattern, for each antenna set, and selects an antenna set with the sum being the highest. Switch 120 connects received signals only from antennas belonging to the selected antenna set to reception RF sections 121 to 124. Received signal inputted to respective reception RF sections 121 to 124 are converted into respective intermediate-frequency signals, combined in signal combining section 125, and demodulated in demodulation section 126 to be a desired signal.
