摘要
En 中文
A multi-step scheme is proposed for the input quantization of message-passing decoders for low-density parity-check (LDPC) codes. The proposed scheme, which is applicable to both regular and irregular codes, lowers the error floor significantly at the cost of small increase in complexity, memory and latency.
