Abstract：
 The invention relates to one multi-load frequency expansion communication method based on discrete Fourier exchange sequence, which is characterized by the following: the system transmission data uses one special sequence expansion by use of one certain discrete exchange on multiple load wave due to this cross property, the user data can be divided and sent to ensure data transmission rate and frequency spectrum efficiency.
