Iterative Decoding Algorithms for RS-Convolutional Concatenated Codes

by Meritxell Lamarca Josep, Josep Sala, Alfonso Martínez , 2003
"... This paper presents an iterative decoding algorithm for concatenated codes consisting of a ReedSolomon and a convolutional code, focusing on the code of the DVB-S standard. Existing solutions for the different decoding stages and their interfaces are discussed and their performance is compared. Besi ..."

Measures for Tracing Convergence of Iterative Decoding Algorithms

by M. Tüchler, S. Ten Brink, J. Hagenauer - in Proc. 4th IEEE/ITG Conf. on Source and Channel Coding , 2002
"... We study the convergence behavior of turbo decoding, turbo equalization, and turbo bit-interleaved coded modulation in a unified framework, which is to regard all three principles as instances of iterative decoding of two serially concatenated codes. There is a collection of measures in the recent l ..."

literature, which trace the convergence of iterative decoding algorithms based on a single parameter. This parameter is assumed to completely describe the behavior of the soft-in soft-out decoders being part of the iterative algorithm. The measures observe different parameters and were originally applied

An Iterative Decoding Algorithm of Low Density Parity Check. . .

by T. Wadayama , 2000
"... An iterative decoding algorithm of low density parity check(LDPC) codes for hidden Markov noise channels is presented. The hidden Markov noise channel is an additive noise channel whose noise statistics is modeled by a hidden Markov model(HMM). The proposed decoding algorithm consists of two parts: ..."

Iterative Decoding Algorithms for Turbo Product Codes

by Rodica Stoian, Lucian Andrei Perişoară
"... Abstract:- In this paper we introduce the iterative decoding principle, “the turbo principle”, for the bidimensional Turbo Product Codes (TPC’s). The constituent codes used for encoding on rows and columns are two concatenated (7,4) Hamming block codes. Several Soft Input Soft Output (SISO) algorith ..."

) algorithms can be used for the iterative decoding process. At each iteration, the two decoders decode all rows, then all columns. For particular SISO algorithms, Maximum A Posteriori (MAP) algorithm and Soft Output Viterbi Algorithm (SOVA), the system is simulated and performances, in terms of Bit Error Rate
