引言在短波通信中为使数传机速率高,误码低需要采用先进的频率差分相移键控体制(FDPSK)。该体制要求收端首先能精确地实现动态分路和信息提取。我们这里将要介绍的动态滤波器能很好地完成上述任务。实践证明,它不仅能用于“频率差分相移键控系统”,而且在“时间差分系统”和“频移键控系统”中也同样获得了较好地应用。因此它是一种应用甚为广泛的电子式动态滤波器。
INTRODUCTION In HF communications, advanced frequency differential phase shift keying (FDPSK) systems are required for high data rate and low bit error rates. The system requires that the receiver can accurately implement dynamic taping and information extraction first. The dynamic filter that we will introduce here can accomplish the above tasks well. Practice has proved that it can not only be used in “frequency differential phase shift keying system”, but also in the “time difference system” and “frequency shift keying system” also get a better application. So it is a widely used electronic dynamic filter.
