摘要

本文讨论了MIMO空间复用(MIMO- sm)系统的性能。第一部分比较了在发送端每个天线独立编码的有序连续抵消(OSIC)接收器与在发送端MMSE接收器联合编码的性能。我们表明，后一种系统在低信噪比和中等信噪比的中断吞吐量方面具有更好的性能。第二部分讨论了MIMO-SM系统的接收天线子集选择问题。特别是，我们开发了快速，接近最优的算法，实现了大部分的选择增益。我们还提供了大量的蒙特卡罗模拟，以说明子集选择的性能优势。

Joint MMSE versus V-BLAST and antenna selection

In this paper, we discuss the performance of MIMO spatial multiplexing (MIMO-SM) systems. The first part compares the performance of the ordered successive cancellation (OSIC) receiver, with independent encoding per antenna at the transmitter, with the MMSE receiver joint encoding at the transmitter. We show that the latter system has better performance in terms of outage throughput at low and moderate SNR. In the second half, receive antenna sub-set selection is discussed for MIMO-SM systems. In particular, we develop fast, near optimal algorithms that achieved most of the selection gains. We also present extensive Monte Carlo simulations illustrating the performance benefits of sub-set selection.
