A new technique is proposed for efficient encoding of low density parity check (LDPC) codes using the concept of approximate lower triangulation (ALT). Parity check matrix is preprocessed and encoded in O(n) complexity. This encoding technique is applied in the IEEE 802.11n based H matrix where the complexity is compared with the Richardson algorithm. The proposed adaptive message length (AML) encoding...
Quasi Cyclic Low Density Parity Check codes (QC-LDPC) is proposed to reduce the complexity of the Low Density Parity Check codes (LDPC) further while obtaining the similar performance. Our proposed QC-LDPC presents an improved construction of circulant sub-matrices based QC-LDPC at high SNR. The proposed construction yields a performance gain of about 1 dB at a 0.0003 bit error rate (BER). Proposed...
