Efficient Decoding of Turbo Codes with Nonbinary Belief Propagation
This paper presents a new approach to decode turbo codes using a nonbinary belief propagation decoder. The proposed approach can be decomposed into two main steps. First, a nonbinary Tanner graph representation of the turbo code is derived by clustering the binary parity-check matrix of the turbo code. Then, a group belief propagation decoder runs several iterations on the obtained nonbinary Ta...
متن کاملImproved Turbo Decoding through Belief Propagation
Absfract-It has long been recognized that graphical representations of parallel concatenated codes contain loops. These loops make it extremely difficult to use the standard, probabilistic methods for graphs to obtain any insight as to the functionality of turbo decoding. Graphbased techniques do, however, lead to useful extensions and generalizations of the turbo decoding concept. In this pape...
متن کاملIterative Decoding Algorithms for Turbo Product Codes
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) algorithms can be used for the iterative decoding process. At each iteration, the two decoders decode all rows, then...
متن کاملNear-optimum decoding of product codes: block turbo codes
This paper describes an iterative decoding algorithm for any product code built using linear block codes. It is based on soft-input/soft-output decoders for decoding the component codes so that near-optimum performance is obtained at each iteration. This soft-input/soft-output decoder is a Chase decoder which delivers soft outputs instead of binary decisions. The soft output of the decoder is a...
متن کاملCollaborative Decoding Using Turbo Codes
Cooperative reception allows diversity to be achieved by a group of radios that are not physically connected but that receive independent copies of a message. The receivers achieve diversity by exchanging messages. One such technique is collaborative decoding, in which the receivers iterate between decoding and information exchange. Collaborative decoding has been shown to be effective for conv...
