In the processing of shortwave communication, automatic link establishment(ALE) demands well-performed coding and decoding and a codeword shortly after coding in order to obtain more coding gain and anti-jamming performance. A convolutional coding concept with semi-determinative initial state is proposed along with its coding and decoding algorithm. This algorithm perfectly deals with the conflict between the performance of coding and the codeword length after coding. Being sure of the codeword length, its performance approximated its optimum performance,making it a pragmatic coding and decoding algorithm.
