An orthogonal multi-rate modulation method for modulating a symbol vector made up of a plurality of data symbols is disclosed. The orthogonal multi-rate modulation method includes the following steps: firstly, a precoding matrix, in which the column vectors are mutually orthogonal, is provided. Then, a product of the symbol vector and the precoding matrix is made to generate a precoded vector. Finally, the precoded vector is filtered by a Nyquist Analog Filter, so as to output a complex baseband waveform.
