Abstract :
In this paper, a concatenating coding scheme is proposed for satellite communication, which employs an inner trellis code and RS outer codes. The inner code is a rate 5/6 4-dimensional 8 PSK trellis code based on Viterbi´s pragmatic coding idea. The outer codes are RS(255,239) and NASA standard RS(255,223) codes, respectively. Performance is evaluated by an analytical method and computer simulations under an ideal linear AWGN channel. The complexity and the performance of the considered coding scheme are compared with the same rate optimal four dimensional trellis code and punctured
