摘要
将正交频分复用(OFDM)、码分复用(CDM)应用到多输入多输出(MIMO)系统,给出一种空频联合的SF-VBLAST检测方案,选用了合适的CDM转换矩阵,模拟实验证明该方案具有良好的频率分集性能和高频谱效率。
MIMO can be used with OFDM to improve performance and transmission rate. In this paper we investigate the differences between all kinds of techniques in OFDM-MIMO systems for achieving full diversity or maximum spatial multiplexing gain. As a resuit, if OFDM is combined with other techniques such as channel coding or space time coding, a desired diversity and spatial multiplexing gain can be provided.
