This project considers the iterative decoding of turbo product codes (TPC) with eBCH codes (TPC/eBCH) based on the belief propagation (BP) over magnetic recording channels. The existence of many short cycles in the code graph of eBCH codes seriously degrades the performance of iterative decoding....
