Abstract
A digital code decoding apparatus including a reference waveform storage section which prestores, as reference waveforms, at least m received waveforms corresponding to m possible values of m-value digital codes distorted during transmission, a waveform comparing section which compares at least m reference waveforms read out of the reference waveform storage section and the received waveform, respectively, and a decoded information output section which discriminates one of the reference waveforms which most resembles the received waveform, on the basis of the compared outputs from the waveform comparing section, and outputs, as decoded information, a digital code corresponding to the discriminated reference waveform.
