摘要
本文描述了基于正交小波函数族的多址通信原理，并提出了一种多速率正交小波调制方法用具有不同伸缩尺度的小波函数对不同信道中的码流进行编码，可以达到扩展信息序列频谱的目的，因此这一多址技术具有很好的抗干扰性能．本文还讨论了这一多址方式的其它特点。
The principle of multiple access communication is described, Which is based on the orthogonal wavelets inthis paper. And a multirate orthogonal modulation scheme is proposed. The goal of spreading information equence spectrum ismet by coding bit-streams with the different scaled wavelets. So this multiple access technology has a good perfomance in resisting narrow jam and interference. The other characteristics are also discussed. Some methods are given to resolve the inequity of the channel capacity.
