Performance of turbo coding for satellite UMTS multimedia broadcast multicast services

In this paper the forward link performance of a satellite based UMTS system designed for the delivery of multimedia broadcast multicast services is investigated for different physical layer parameter combinations in AWGN and Rice radio channels. Guidelines for the choice of these parameters are given as a trade-off between bit error rate and processing delay. Also, the effects on the performance of the internal turbo interleaver and of the inter- and intra-frame interleavers are analyzed and described.
