Wireless base station that staggers the transmission of symbols to spatially multiplexed mobile stations by a predetermined time that is shorter than the symbol period

摘要

When signals for two mobile stations PS-A and PS-B are multiplexed using path division, a clock generating unit 52 generates a clock signal so as to delay the timing for transmitting symbols to the mobile station PS-B by 0.5 symbol periods relative to the transmission of symbols to the mobile station PS-A. If the transmission timing is adjusted in this way, a mobile station that picks up symbols which are spatially multiplexed with the signal for the present mobile station but are intended for another mobile station will not be synchronized with the symbols for the other mobile station. The mobile station will not be able to properly demodulate the symbols for the other mobile station, and so can be prevented from outputtin
