摘要
针对已有同步误差分析考虑因素不全,不符合实际连续数据传输系统等缺点,提出一种研究同步误差对MIMO-OFDM系统性能联合影响的分析方法,推导了同步误差联合干扰下系统解调信号和均值信干比表达式,通过在AWGN信道和多径衰落信道下对系统性能仿真,结果表明了分析方法的可行性。
Focusing on the disadvantages of existing analysis which considers factors incomplete and inconsistent with the actual continuous transmission system,this paper proposed a method of studying joint influence of synchronization error on MIMO-OFDM system.The expression of demodulate signal and mean signal interference ratio(MSIR) were derived under the joint interference of synchronization error.By simulating system performance in additive white Gaussian noise(AWGN) channel and multipath fading channel,the result indicates the feasibility of the method.
