Abstract:
1. A communication system in which a signal to be transmitted is divided into N and transmitted from N transmitters, and the signals transmitted from said N transmitters are received by M receivers (M≧N), the signals transmitted from said N transmitters being synthesized in each of said M receivers, said system comprising, in each of said M receivers to be paired as defined beforehand with each of said N transmitters: control information generation means for generating transmitter power control information for the transmitter paired with the receiver, based on the received signal from the transmitter paired with the receiver; and transmitting means for transmitting said transmitter power control information to the transmitter paired with the receiver, wherein said control information generation means generates said transmitter power control information based on the reception power level of said received signal from the transmitter paired with the receiver, and wherein said control information generation means generates said transmitter power control information in accordance with a comparison result of comparing said reception power level with a predetermined power level.
