Adaptive Cochannel Interference Cancellation in Space-Time Coded Communication Systems
IEEE TRANSACTIONS ON COMMUNICATIONS, VOL. 50, NO.10, OCTOBER 2002，-0001，（）：
Space-time coding is a powerful scheme that combines channel coding, modulation, and multiple transmit antennas to achieve higher data rates and combat fading in wireless systems. In this letter, we propose a multiple-input multiple-output minimum mean-square error spatial-filtering-based daptive antenna arrays method to suppress cochannel interference (CCI) in space-time coded systems. It is shown that the proposed method can effectively suppress CCI while preserving the space-time tructure, thereby significantly improving the system's interference suppression ability without significant bit error rate performance degradation.
