Throughput analysis of ATM traffic over satellite links using ARQ and adaptive concatenated FEC codes
In this paper, we analyze the performance of an adaptive hybrid FEC/ARQ scheme that adjusts the code rate to match the channel conditions. The concatenated scheme is using a fixed-rate RS(59,53) over GF(2/sup 8/) as the outer code along with a rate-compatible punctured convolutional RCPC code as the inner code. The inner code has order 6 memory and its rate is 1/2, 4/7, 2/3, 4/5, or 8/9, depending on the channel conditions. The performance of the adaptive scheme is compared with two fixed-rate-concatenated schemes whose inner code rates are 2/3 and 1/2.
