摘要

我们研究了一种具有递归空间复用(RSM)的闭环多输入多输出(MIMO)架构在共信道干扰存在下的性能。即使MIMO信道在帧与帧之间任意变化，RSM也是有效的。RSM方案避免了零强迫(ZF)和最小均方误差(MMSE)接收机固有的噪声增强，也避免了V-BLAST接收机日益增加的复杂性。使用蒙特卡罗模拟，结果表明RSM优于传统的ZF和MMSE接收器，并且在存在同信道干扰的情况下是一种有趣的方法。

Recursive spatial multiplexing in the presence of time-variant co-channel interference

We investigate the performance of a closed-loop multiple-input multiple-output (MIMO) architecture featuring recursive spatial multiplexing (RSM) in the presence of co-channel interference. RSM is effective even when the MIMO channel varies arbitrarily from frame to frame transmission. The RSM scheme evades the noise enhancement inherent in zero forcing (ZF) and minimum mean squared error (MMSE) based receivers and also avoids the increasing complexity that arises in V-BLAST receivers. Using Monte-Carlo simulations, it turns out that RSM outperforms the conventional ZF and MMSE receivers and is an interesting approach in the presence of co-channel interference.
