摘要： A downlink line signal transmitted during a guard interval determined by using a delay profile made accurately with an uplink line COMA signal is received by an MS, the preamble portion of the downlink line signal is Fourier-transformed, and demodulated. The transmission parameters (guard interval, subcarrier frequency interval, number of subcarriers) contained in the preamble portion are extracted and outputted to a Fourier transform block (303). The data portion is Fourier-transformed according to the extracted transmission parameters by the Fourier transform block (303). The Fourier-transformed signal is demodulated by a demodulating block (304) and outputted as reception data. Thus, the delay profile used for determining the guard interval can be accurately made. Therefore the transmission quality is ensured, and the frequency use efficiency is improved.

摘要： 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.

摘要： Block likelihood calculators 106-1 to 106-n calculate likelihood of each symbol included in a received signal, thereafter setting likelihood for rank decision from the calculated likelihood on a predetermined block-by-block basis. A rank decider 109 decides a rank with respect to each symbol included in the predetermined block based on the set block likelihood on the block-by-block basis. A re-spreader 110 spreads the symbol whose rank is the highest on the block-by-block basis, and a subtracter 111 removes the spread symbol from the received signal on the block-by-block basis.

摘要： A directivity control section 103 performs weight control over a received signal using channel estimation and optimum weights, performs processing such as generation of the received signal and generates a plurality of weight-controlled transmission signals. A received signal demodulation section 104 extracts an SIR measurement result from the received signal. A scheduler section 105 decides which terminal should be assigned to a channel to be adaptively modulated from the SIR measurement result and at the same time decides the modulation multi-valued number and coding rate of the signal to the terminal. A transmission signal generation section 106 modulates a transmission signal such as a reference signal or packet data. A directivity switching instruction section 107 controls switching between directivities so as to maintain the same directivity after the reference signal is transmitted with a directivity until packet data is transmitted with a directivity. This makes it possible to receive packet data with high quality, improve efficiency of a radio frequency band and maximize communication path utilization efficiency.

摘要： Scheduler 304 performs scheduling such that the communication terminal apparatuses to transmit packets to are determined according to the order in CIR information output from demodulator 303, and determines the modulation schemes and coding rates of the packets. Command detector 305 detects an ARQ command transmitted from the communication terminal apparatus determined in scheduler 304, outputs an ACK/NACK signals to buffer 306, and outputs a SUSUPEND signal or a GIVEUP signal to scheduler 304. Scheduler 304 stops retransmission upon receiving a SUSPEND signal or a GIVEUP signal from command detector 305, and redoes the scheduling. Thus, it is possible to improve overall system throughput in a wireless communication system that performs packet transmission.

摘要： Of systematic bits (S) and parity bits (P 1 , P 2 ) 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.
