Abstract
A method is disclosed that divide a total frequency band of a communication system into several equally spaced non-overlapping information channels, which are allocated to different users; the information channels are in one-to-one correspondence with the users; user signals from different addresses are distinguished based on frequency, thereby completing the multiple access connection; and duplex communication between two users uses a fundamental frequency and harmonics for information transmission. A process of the information transmission is as follows: different information is first modulated and then is separately loaded on different harmonic components, different information is transmitted through different harmonic components or component combinations so that each pair of information channels can transmit N groups of different information at the same time, and finally the fundamental frequency and harmonic information received by a receiving end is demodulated to obtain all the transmitted information.
