Abstract
The present invention provides a signal modulation method. The method includes: generating a transmit signal pulse waveform, where a width of the pulse waveform is τ, each pulse waveform is associated with n symbols (n>1), a width of each symbol is Δτ, and performing an operation on every n consecutive symbols in a to-be-sent symbol flow and the pulse waveform according to a preset operation manner, to generate an associated signal of the symbols and the pulse waveform; and sending the associated signal by using a transmission channel. The present invention helps improve spectral efficiency of a system. In addition, symbols are mutually constrained based on a correlation between the symbols, and information symbols are scattered to a plurality of symbols, thereby helping improve a capability of resisting noise and attenuation by a signal.
