In this paper, we present a rate-compatible LDPC decoder architecture which supports code rates between the rate of the mother code and 1. The rate-1/2 2304-bit Quasi-Cyclic (QC) LDPC codes with dual-diagonal parity check structure is selected from WiMax standard as the mother code and is punctured using specific puncturing patterns to obtain arbitrary rates. Parallel layered decoding architecture...
