摘要

本文描述了含随机编码的振幅键控（ASK）、移频键控（FSK）、移相键控（PSK）信号的功率谱密度

给出了适于用计算机识别功率谱密度的某些特征

着重介绍了在干扰背景下预测信号的参数。一个例证的结果是满意的。

Abstract

This paper describes the power spectral densities of three kinds of random coded signals

ASK

FSK and PSK

and presents some characteristics suitable for computer recognition of power spectral densities. Much efforts have been made to estimate parameters of these signals under strong background interferences. An example is given with satisfactory results.
