频率选择性衰落信道中的发射分集设计
Transmit Diversity Design in Frequency-Selective Channel
【摘要】 为了获得多天线分集以对抗衰落,提出了一种适用于频率选择性衰落信道的发射分集方案.该方案利用零相关窗互补码的理想相关特性分离多径,最终同时得到全部的空间分集增益和频率分集增益.仿真结果表明,与频率选择性衰落信道下的空时编码方案相比,该方案发射接收装置的结构更简单,设计更灵活.
【Abstract】 In order to obtain space diversity to fight channel fading,a transmit diversity scheme applicable to frequency selective channel is proposed.With zero correlation zone complementary codes,both full space diversity and full frequency diversity can be obtained.Simulation proves this scheme has same performance compared to original diversity design in frequency-selective channel presented by previous research.Its transmitter and receiver structure are much simpler than the previous one,and shows more flexibly.
