Because of limited frequency band of channel, spread spectrum and MFSK modulations can not resolve that high speed transmission is in contradiction with limited frequency band.───进行高速水下通信时，由于水下信道的频带有限，扩频和MFSK调制方式无法解决高速率信息传输和可利用信道频带窄的矛盾。
FFT algorithm can provide better extrapolation performance and more ac-curate spectral estimates than other developed algorithms for the band-limited signals with a smooth spectrum.───推性能和谱估值方面比以往的方法好。由于采用了FFT和收敛加速因子，它是一种实用的算法。
The out band spurious spectrum is limited by raised cosine filter in transmitter, and the shadow effect can be removed by combining the signal power of two branches in receiver.───的反射电路用升余弦滤波器抑制带外频谱，而接收电路可以用功率合成的方法消除的盲点效应。
