Zusammenfassung:	Disclosed in the present application are an M-FSK modulation-based receiver and a reception method therefor. The method comprises performing M-FSK demodulation on a frame structure comprising a preamble frame, a sync frame, and a data frame, and specifically comprises: utilizing an autocorrelation time-frequency synchronization technique to perform M-FSK demodulation of a repetitive sequence preamble frame; utilizing a cross-correlation sliding FFT time-frequency synchronization technique to perform M-FSK demodulation of a non-repetitive sequence preamble frame; and utilizing an adaptive scalable FFT M-FSK data demodulation technique to perform M-FSK demodulation of the sync frame and the data frame. Utilizing the technical solution of the present application allows advanced M-FSK to achieve lower sensitivity, and is also suitable for various multi-path and Doppler scenarios.
