Abstract
A adaptive deciding method and apparatus for frequency shift key signals are provided to sample the demodulated FSK signal, input the values of the sample points in sequence to a sample group, and compare at least a pair of the sample points, thereby finding out the central point of the FSK signal to improve decoding due to signal attenuation.
