摘要

本文提出了一种基于单载波频域均衡(SC-FDE)技术的多用户多输入多输出(MIMO)系统，用于频率色散多径环境下信号受同信道干扰(CCI)和码间干扰(ISI)的干扰。该方案能有效地同时抑制CCI和ISI，且复杂度较低。此外，它对可用天线的数量没有任何限制。仿真结果表明，该方案提高了误码率和吞吐量，优于多载波系统。该方案将使多用户选频MIMO系统更具实际可行性。

A Multi-user SC-FDE-MIMO System for Frequency-Selective Channels

This paper proposes a multi-user multiple input-multiple output (MIMO) system based on a singlecarrier frequency-domain equalization (SC-FDE) technique for frequency-dispersive multipath environments, where the signals are corrupted by both co-channel interference (CCI) and intersymbol interference (ISI). The proposed scheme effectively suppresses both CCI and ISI simultaneously with relatively low complexity. Furthermore, it does not impose any restriction on the number of available antennas. Simulation results show that the proposed scheme offers improved bit error rate and throughput performance and is superior to multi-carrier systems. The proposed scheme will make the multi-user MIMO system for frequency-selective channels more practically feasible.
