通信确知信号频谱分析

Frequency-domain Analysis of Deterministic Signal

通信系统中的信号包括确知信号和随机信号;信号分析包括时域分析和频域分析.本文分析了通信中要进行信号频域分析的缘由,并以确知信号为研究对象系统地阐述了频域分析的来龙去脉.

The signal in communication system include deterministic signal and random signal, signal analyses also have time- domain analysis and frequency- domain analysis. The reasons that we analyze frequency- domain signal in communication system were given in this paper, and the source and development of frequency - domain analysis wet comprehensively described by taking the deterministic signal as the researching object.
