摘要：

We apply a simple transmit diversity technique to downlink multicarrier CDMA (MC-CDMA) systems. The resulting diversity on each subcarrier improves orthogonality among users, which is distorted by the subcarriers' multipath fading. Accordingly, the diversity suppresses multiuser interference. For equal-gain-combining (EGC) receivers, both theoretical analysis and simulation results show that interference is approximately reduced by half compared to MC-CDMA without space diversity. For the orthogonality-restoring combining (ORC) receiver, simulation results show that it suppresses noise amplification while rejecting multiuser interference.
