Abstract
An OFDM signal modulation method based on compressed sensing is provided, the method includes: acquiring a demodulation parameter of a receiver, where the demodulation parameter includes Tof a periodic square signal of the receiver in sampling, Tis a length of a minimum timeslot during which the periodic square signal maintains a high level or a low level; performing an OFDM modulation on an inputted information symbol to generate an OFDM baseband signal, and controlling a sampling interval T=T/k of the OFDM baseband signal to be integral multiple of T, where Tis a duration of valid data in the OFDM baseband signal, and k is the number of sub-carriers in the OFDM baseband signal; and up-converting the OFDM baseband signal and transmitting the processed signal to the receiver. Also provided are a demodulation method, device and system.
