This paper addresses the issue of encoding of LDPC codes for certain transmission standards that employ LDPC as coding scheme. It is shown that for these LDPC codes, the encoding can be done simply by reusing decoding resources with negligible overhead. Compared to conventional encoding designs, our approach requires much less resources specified for encoder.
An efficient early stopping method is proposed in this paper to reduce the average number of iterations for low density parity check (LDPC) decoders. The method is very efficient especially when the channel signal-to-noise ratio (SNR) is low. It is based on the estimation of the log-likelihood ratio (LLR) messages of the check nodes.
