Abstract

Low-density parity check (LDPC) codes which have many encouraging characteristics, such as the lower complexities of the hardware implementation, closing to Shannon limit and no patent barrier, have gradually regained the interests of researchers. We present performance simulations in allusion to QC-LDPC codes. A fast double-recursion pipeline method which can significantly improve the encoding speed and a normalization min-sum algorithm are proposed in this paper. Simulations, hardware implementation and real test showed that QC-LDPC codes which has strong advantages on resource consumption, delay constraint and coding gain, could serves as an appealing alternative to new generation satellite navigation channel encoding and decoding.
