Abstract
At base station 101, information signals for mobile station (1) are distributed, each spread with a different spreading code then transmitted from two antennas (3) and (4) assumed under good condition in radio propagation. In mobile station (1), composed waves of both signals are received and each is despread with respective spreading code, as well as in mobile station (2). According to it, it is possible to transmit the same information from a plurality of different antennas at the same time, which prevents the deterioration in communication quality in the case where a wrong antenna is selected or the radio propagation condition varies fast.
