摘要
研究了削波后的甚低频大气噪声中的通信接收性能。通过对削波后的甚低频大气噪声建立数学模型,分析了大气噪声中甚低频接收机的误码率性能,并进行了仿真。结果表明,不同饱和幅度下,分析结果均与仿真结果一致。
In this paper the performace of communication receiver in clipped very low frequency（VLF） atmospheric noise is studied. A mathematical model for the clipped VLF atmospheric noise is presented, and the bit error rate（BER） performance for binary phase shift keying（BPSK） receiver is analyzed based on the model. Simulations are performed at different clipping levels, and the results show that the gained theory conclusion is in agreement with the simulations.
