PROBLEM TO BE SOLVED: To provide a wireless transmitter, a wireless receiver and a wireless communication system, in which occurrence of adjacent channel interference is suppressed even if Doppler broadening occurs.SOLUTION: A wireless transmitter includes a differential space-time coding modulation circuit (i.e., first through Nth DSTBC modulation circuits 62, 63, 64) for encoding the transmission data paralleled to N by differential space-time coding system, and generating N single carrier signals for M systems, and frequency shift circuits 71, 72 for changing the frequency of the N single carrier signals for each system. The transmission frequency shift circuits 71, 72 change the frequency of the N single carrier signals, in a direction for widening the interval of the center frequencies of adjoining single carrier signals. |
