ABSTRACT:
In a digital communication system including a coder and a decoder, a predefined known data signal is combined by the coder with a sequence of input signals at a predefined time interval and are subjected to convolution coding to send convolution code sequence to the decoder The decoder is supplied with the convolution code sequence as a sequence of reception codes to decode the reception codes into a sequence of decoded signals with reference to the predefined known data signal by the use of a maximum likelihood decoding method.
