中文摘要	A two stage belief-propagation (TSBP) decoding algorithm was developed based on trapping set state (TSS) detection to reduce the error floor of low-density parity-check (LDPC) codes. The algorithm uses belief-propagation algorithm until the TSS is detected, then iterative decoding is attempted to continue through flipping and augmenting the initial values of the possible error bits until the decoding succeeds or the maximum number of attempts is reached. Simulations show that the algorithm significantly reduces the maximum number of iterations for decoding in the error floor region, and with a few additional attempts, the error floor of LDPC codes can be reduced by nearly two orders of magnitude.
