摘要：

为定量分析脉冲熄灭产生的子载波间干扰对正交频分复用(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OFDM接收机解调器输出信噪比的计算公式,并以此为基础,定量分析脉冲熄灭对OFDM接收机符号差错性能的影响.计算机仿真结果表明,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.

关键词: 正交频分复用, 脉冲熄灭, 频率选择性瑞利衰落

Abstract:

To analyze the impact of inter carrier interference caused by pulse blanking on the error performance of orthogonal frequency division multiplexing (OFDM) receiver,an analytical expression of the signal to noise ratio for OFDM receiver with pulse blanking was derived in frequency selective Rayleigh fading channel, the impact of pulse blanking on the symbol error ratio for OFDM receiver was also analyzed quantitatively. Simulation results validate the accuracy of the derived formulas.

Key words: orthogonal frequency division multiplexing, pulse blanking, frequency selective Rayleigh fading
