| 摘 要： | 在对潜通信中，甚低频（VLF）最小频移键控（MSK）调制信号是通常使用的信号形式。由于海浪的浪高与甚低频电波在海水中的波长可比拟，所以海浪对通信的影响不可忽视。在考虑海浪和高斯噪声影响的情况下，用计算机仿真给出MSK差分解调的误码率，分析了海浪波高和信噪比对通信解码误码率的影响。

| Abstract: | Minimum shift keying(MSK) signal of very low frequency(VLF) wave is usually employed in submarine communication.The influence of sea waves on communication can not be ignored because of the height of sea wave and the wavelength of VLF wave in sea water are comparative.In this paper,the bit error rate(BER) of differential demodulation is obtained by computer simulation in consideration of sea waves and Gaussian noise.The effect of the height of sea wave and signal-to-noise ratio(SNR) to BER on communication ... |

| Keywords: | sea wave the height of wave MSK BER SNR |
