在各种通信应用中，小波变换被用作短时傅立叶变换的替代方法，用于非平稳数据的频谱分析，或者作为一种新的工具，在时域和频域分析之间架起桥梁。本文概述了小波理论及其在通信问题中的应用。我们讨论两个例子。一个涉及使用小波作为设计工具，在多址通信系统中的时间和频率分析的桥梁。另一种是将小波变换用于扩频通信中的变换域切除。为了详细研究小波及其在信号表示、带宽压缩、杂波抑制、识别和多分辨率信号处理中的许多用途，读者可以参考一些关于这一主题的优秀评论文章和参考文献。
Wavelets are being utilized in various communications applications either as an alternative to short-time Fourier transform for spectral analysis of non-stationary data or as a new tool to bridge between time domain and frequency domain analysis. The article provides an overview to the theory of wavelets and its application to communication problems. We discuss two examples. One involves using wavelets as a design tool to bridge time and frequency analysis in multiple access communication systems. The other involves using wavelets in transform domain excision in spread spectrum communication. For a detailed study of wavelets and their many uses in signal representation, bandwidth compression, clutter suppression, recognition, and multiresolution signal processing the readers are referred to a number of excellent review articles and references on this subject.
