Abstract

RS codingandbyte interleavingin CMMB systemare jointly designed based on segment processing mechanism. The proposed scheme reduces storage space so greatly that byte interleaving can be completed inside a popular FPGA chip instead of a largeexternal memory, leading to lower cost, faster speed and higherreliability.Moreover, contraposeto the segment processing mechanism,this paper gives an optimizedRS encoder, which quickens the coding rate with almostthe same hardware implementation complexity.
