摘要
提出了1种可以应用于频率选择性衰落信道的多天线最小移频键控(multiple-input multiple-output minimum shift keying,MIMO-MSK)均衡解调方案,并研究了对应的信道估计算法。通过不同的多径信道对整个系统的性能进行仿真,仿真结果表明,所提出的MIMO-MSK系统方案可以有效地对抗频率选择性信道和信道的非线性失真。
A multiple input multiple output minimum shift keying (MIMO-MSK) equalization scheme is proposed for frequency selective channels. The corresponding channel estimation algorithm is also investigated. The performance of the whole system un-der different multipath channels is simulated. It is shown that the MIMO-MSK system can effectively resist the frequency selec-tive channels and the channel non-linearity.
