Claim 0:
1. A frequency division multiple access communication method based on harmonic modulation technology, wherein a total frequency band of a communication system is divided 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 a multiple access connection; and duplex communication between two users uses a fundamental frequency and harmonics for information transmission, realizing use of a pair of frequency channels to communicate with different users at the same time;
wherein 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 so that each pair of information channels can transmit N group of different information at same time, and finally the fundamental frequency and harmonic information received by a receiving end is demodulated to obtain all the transmitted information.
