摘要
研究了联合检测中的迫零线性均衡ZF-BLE算法和最小均方误差线性块均衡MMSE-BLE算法,在此基础上比较了MMSE-BLE和ZF-BLE在不同信道的冲激响应,不同的噪声协方差和单天线,智能天线环境下的性能,通过对上行和下行线路的仿真比较,得出了MMSE-BLE算法的性能要优于ZF-BLE算法的结论。
In this paper, we analyze two kinds of joint detection algorithms ZF-BLE and MMSE-BLE. In theory, we compare their performance by computation and the ability of resisting ISI and MAI. Also, given different channel-impulse responses, various noise covariance matrix, single or smart antennas, we simulate their performance in up-link and down-link. Then we achieve conclusion that MMSE-BLE is better than ZF-BLE.
