摘要:

为了研究信道相关性对空频系统性能的影响,介绍了频率选择性空间相关信道的频域模型,并在此基础上分析了空频系统的频域成对差错概率. 基于最小均方误差准则推导和仿真了空频均衡器的性能. 分析和仿真结果表明,空频系统的性能随信道相关性的增加而下降.

关键词: 频率选择性, 相关信道, 空频均衡

Abstract:

The model of correlated multiinput multioutput (MIMO) frequencyselective channels in frequency domain is introduced. And the pairwise error probability (PEP) of spacefrequency systems is analyzed based on this model. Then, the performance of spacefrequency equalizer (SFE) is derived and simulated based on minimum mean square error (MMSE). Analysis and simulation results show that the performance of spacefrequency systems degrades with the increasing of correlation.

Key words: frequency selective channels, channel correlation, spacefrequency equalization
