Turbo code and Low Density Parity Check (LDPC) code are both recommended as FEC code in many communication standards owing to their impressive error correcting performance. Aiming at the common architecture which can decode both of the two codes, this paper describes the method of decoding turbo codes with message passing algorithm which is conventionally used for LDPC codes. In this method, turbo...
In this paper, we study the convergence behavior of distributed iterative algorithms with quantized message passing. We first introduce a general iterative function evaluation algorithms for solving fixed point problems distributively. We then analyze the convergence of the distributed algorithms, e.g. Jacobi scheme and Gauss-Seidel scheme, under the quantized message passing. Based on the closed-form...
