ABSTRACT:
A radio communication system is capable of realizing a space diversity with single channel of an antenna and a receiver in a mobile communication equipment or by assigning one spread code. The radio communication system includes a base station and a mobile station. The base station effects spread spectrum of a transmission signal for outputting a spread signal, delays the spread signal for a predetermined delay period for outputting a delayed signal and transmits a signal derived by adding the delayed signal and the spread signal.
