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.
