摘要：
In this paper, we show how to construct generalized low-density (GLD) codes from turbo product codes (TPCs). By means of this construction, we propose a novel so-called Chase-MP algorithm for iterative decoding of a TPC by using the bipartite graph of the constructed low-density (LD) matrix. Experimental si- mutations for a Hamming-component TPC on the additive white Gaussian noise (AWGN) channel are also provided. In comparison with the conventional serially iterative Chase-2 algorithm, the Chase-MP algorithm is more convenient for fully parallelizable iterative deco- ding and can achieve better performance.
