Abstract :
Digital satellite network is modeled by a set of discrete memoryless channels (DMCs), which reduce to three simple cascade binary symmetric channels (BSCs) for information transmission. The results of channel improvement due to specific error correction are asymptotically or numerically demonstrated in terms of channel capacity, transmission efficiency, message delay, bandwidth conservation and ease message traffic congestion.
