Implementation of a self-orthogonal convolutional code used in satellite communications

A rate-7/8 self-orthogonal convolutional-code implementation is discussed. The codec uses a majority logic threshold technique for decoding the encoded data stream. The error performance of the code in a binary symmetrical channel in presence of white Gaussian noise is investigated and the input/output bit error-rate bound for the codec is computed and compared to another 7/8-rate codec that has already been implemented.
