In the tornado code, cascading with traditional erasure codes (mostly Reed-Solomon codes) is always used to protect the last level, which will enhance the erasure correcting performance. However, this method increases the complexity in the process of encoding and decoding. In this paper, we introduce an improved algorithm to get linear coding complexity and simplify the implementation of decoder in...
The analog low-density parity-check (LDPC) decoder, which is a specific application of the probabilistic computing, is considered to be a promising solution for power-constrained applications. However, due to the lack of efficient electronic design automation tools and reliable circuit model, the analog LDPC decoders suffer from costly hand-craft design cycle, and are unable to provide enough coding...
The analog implementation of error control decoders is a competitive methodology compared with the digital implementation in power efficiency and throughput. In order to detect uncorrectable frames and early stop the iterative decoding of low-density parity check (LDPC) analog decoders, a probability stopping block using probabilities of satisfied checks is proposed. Simulation results show that the...
