Abstract
In a communication system including a plurality of pairs of a transmitting deviceand a receiving device, the transmission performance in the pairs is to be improved. The transmitting device-transmits a transmission signal s(t) to the receiving device-a plurality of number of times. The receiving device-updates the weight matrix Wand the hopping pattern Pused by the FIR filter which performs filtering on the transmission signal r(t) at a predetermined time interval. The receiving device-transmits the updated hopping pattern Pto the transmitting device-. The transmitting device-receives the hopping pattern Pto be used for subsequent spread spectrum.
