Abstract :
A hybrid multilevel error control with an early-stop ARQ scheme was proposed previously. In this scheme, the source traffic is segmented into a number of blocks, each with m cells, then encoded into k (k>m) cells. The transmission of one block may be finished as long as m out of the k cells are received correctly. This paper is an attempt toward a more careful study of the scheme. In particular, the throughput efficiency with parameters (m,k) are derived analytically. The cell retransmission probability with Rayleigh fading channel is investigated by means of simulation. The results show that this scheme can reduce cell-retransmission probability and improve network throughput over a wide range of channel error rate by choosing appropriate parameters m,k
