摘要
在多用户多输入多输出无线通信系统网络中,如何实现各对用户间的高速率、高可靠数据传输是目前国内外重点关注的一项关键通信技术.针对具有两对用户且每个用户均装配四根天线的网络模型,提出了一种能够实现全速率传输并能获得全分集误码性能的编码传输方案.仿真结果表明所提编码传输方案具有有效性.该方案可以进一步拓展到多用户多天线的情况.
In multi-user MIMO wireless network communication system, how to achieve high rate and highly reliable data transfer between each pair of users is a key communication technology. In this paper, a coding scheme based on the network model which could achieve full-rate transmission and full diversity BER performance was proposed. The proposed scheme had two pairs of users and each user was fitted to four antennas. The simulation results confirmed the validity and correctness of the proposed coding transmission scheme. The scheme could be further extended to multi-user multi antenna case.
