摘要:

为定量分析脉冲熄灭产生的子载波间干扰对空时分组编码正交频分复用(space-time block coding-orthogonal frequency division multiplexing,STBC-OFDM)接收机差错性能的影响,在频率选择性瑞利衰落信道下理论分析给出脉冲熄灭STBC-OFDM接收机输出信噪比的计算公式,并以此为基础,定量分析了脉冲熄灭对STBCOFDM接收机符号差错性能的影响. 计算机仿真结果表明,论文给出的理论结果与仿真结果完全一致,验证了理论分析的正确性。

Abstract:

To analyze the impact of inter-carrier interference (ICI) caused by pulse blanking on the error performance of the space-time block coding-orthogonal frequency division multiplexing (STBC-OFDM) receiver, the analytical expression of the signal-to-noise ratio (SNR) for the STBCOFDM receiver with pulse blanking is derived over the frequency selective Rayleigh fading channel, and the effect of pulse blanking on the symbol error ratio (SER) for the STBC-OFDM receiver is also analyzed quantitatively based on the SER expression. Simulation results validate the accuracy of derived formulas.
