PROBLEM TO BE SOLVED: To effectively utilize few frequencies and to increase capacity by applying an interference elimination technique of separating respective reception signals of SIC (Successive Interference Canceller) or the like.;SOLUTION: At the time of transmitting signals on the channel of the same space, time, and frequency, each radio transmitter autonomously changes transmission power according to a predetermined hopping pattern. A radio receiver is mounted with the SIC and detects desired signals and interference signals. Since power hopping is performed by respectively different hopping patterns for the transmission output of the respective signals, a desired relation is satisfied between the reception power of the respective signals and thus the signals are separated.;COPYRIGHT: (C)2003,JPO
