Serially concatenated coding for PR system with LDPC and PC codes
Description
Summary form only given In this work, the coded partial response (PR) system based on serially concatenated error control codes is described. The component codes of the concatenated codes are a low density parity check (LDPC) code and a punctured convolutional (PC) code. In our system, the LDPC code is used as an inner code and is an important random code which can approach Shannon's capacity limit. A practical decoding method of the LDPC code is known as the sum-product decoding algorithm or belief propagation. Furthermore, the PC code is used for an outer code and can enhance the minimum squared Euclidean distance for the coded PR system. The sequence of the PC code has a single parity check capability for the concatenated coding.
