Capacity-Approaching Non-Binary Turbo Codes: A Hybrid Design Based on EXIT Charts and Union Bounds
IEEE Access, 2018 In this paper, we introduce a novel design approach for capacity-approaching non-binary turbo codes. There are two important factors that impact the performance of turbo codes in general: 1) the convergence behavior of iterative decoding in the low ...

Wireless MIMO Systems Employing Joint Turbo-Like STBC Codes With Bit-Level Algebraically-Interleaved URSCs [PDF]
, 2013 In this paper, permutations constructed based on algebraic derivations which are of particular interests due to better error-rate performance as well as simpler and practical hardware implementations, have been used in designing high performance fully ...

EXIT Chart Aided Design of Periodically Punctured Turbo Codes [PDF]
, 2010 EXtrinsic Information Transfer (EXIT) charts have proved to be an effective tool for studying the convergence behaviour of iterative decoders. However, classical EXIT chart analysis fails to assess the performance of turbo codes in which the systematic ...

Annales Des Télécommunications, 2005 The main problem with the hardware implementation of turbo codes is the lack of parallelism in the MAP-based decoding algorithm. This paper proposes to overcome this problem by using a new family of turbo codes called Multiple Slice Turbo Codes. This family is based on two ideas: the encoding of each dimension with P independent tail-biting codes and a

An EXIT-Chart Aided Design Procedure for Near-Capacity N-Component Parallel Concatenated Codes [PDF]
, 2010 Shannon’s channel capacity specifies the upper bound on the amount of bits per channel use. In this paper, we explicitly demonstrate that twin-component turbo codes suffer from a capacity loss, when the component code rate is less than unity, which is ...

Turbo codes and turbo algorithms
Journal of Communications Software and Systems, 2017 In the first part of this paper, several basic ideas that prompted the coming of turbo codes are commented on. We then present some personal points of view on the main advances obtained in past years on turbo coding and decoding such as the circular trellis termination of recursive systematic convolutional codes and double-binary turbo codes associated
