摘要： PROBLEM TO BE SOLVED: To provide a wireless communication system for enabling low power consumption at the use of a control channel and the efficient utilization of frequency band resources, and to provide a transmitter, a receiver, and a transmitter-receiver. SOLUTION: In the case of using a data channel, a modulation signal is subjected to serial parallel conversion (402) and Fourier inverse transform (403) to generate a quadrature frequency multiplexing signal and the signal is transmitted by the multicarrier system. In the case of using the control channel, switches (418, 419) are changed over and the modulation signal is transmitted by the single carrier system without applying the Fourier inverse transform to the modulation signal. Thus, the power consumption in the case of using the control channel is lowered and in the case of communicating a voice signal and a data signal or the like, the frequency utilizing efficiency can be improved.

摘要： PROBLEM TO BE SOLVED: To enable throughput concerning a mobile station, to be improved, located in the vicinity of a boundary of a base station service area, thereby making throughput more uniform at each location within the base station service area. SOLUTION: Base stations BS1-BS6 perform an adaptive modulation based on a reception quality at a mobile station MS. The base stations BS1-BS6 permit an auxiliary transmission of information to the mobile station MS located in another station cell, if a traffic within their own cells is equal to or less than the first threshold value. If the mobile station MS can receive a pilot signal transmitted from the base stations BS1-BS6 whose auxiliary transmission is permitted with a reception intensity of equal to or more than the second threshold value, the mobile station MS requests the auxiliary transmission from the base stations BS1-BS6 and receives the auxiliary transmission from the base stations BS1-BS6. The mobile station MS combines information signals transmitted from the base stations BS1-BS6 in the zone with the auxiliary information signals transmitted, thereby improving the reception quality.

摘要： PROBLEM TO BE SOLVED: To provide a rake receiver capable of improving resistance to multipath and fading in the circuit constitution of a small scale. SOLUTION: One of reception signals frequency-converted in frequency conversion circuits 21-2n is successively selected in a changeover cycle t1 in a selection circuit 30, inputted to a matched filter 401 and demodulated there by repeatedly multiplying a code for timing detection to the reception signal by a cycle t2. The demodulated signals are averaged over plural frames for each cycle t2 in an averaging circuit 402, then the power level is detected in a reception path selection circuit 50 and then, the (m) pieces of timings capable of obtaining a high-order demodulation power level are detected among the reception signals outputted by the frequency conversion circuits 21-2n and allocated to inverse diffusion circuits 71-7m. Also, the selection circuits 61-6n are changeover- controlled so as to select the reception signals corresponding to the timing by the reception path selection circuit 50.
