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 proposed criterion can greatly reduce the average number of iterations at low SNR, and has better tradeoff between complexity and performance than other stopping criteria using extrinsic information.
