摘要
MIMO-OFDM系统利用了时间、频率和空间三种分集技术,使无线系统对噪声、干扰、多径的容限大大增加,同时可以获得高传输速率.研究使宽带MIMO-OFDM系统获得全分集和最大空间复用增益的各种技术,并通过模拟实验证明空间复用技术结合信道编码和空时编码可以得到高分集增益和空间复用增益.
MIMO can be used together with OFDM to improve performance and transmission rate.The differences among all kinds of techniques in OFDM-MIMO systems for achieving full diversity or maximum spatial multiplexing gain are investigated.As a result,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.
