Parallel decoding of turbo codes using multi-point trellis termination and collision-free interleavers [PDF]
, 2009 The UMTS turbo encoder is composed of parallel concatenation of two Recursive Systematic Convolutional (RSC) encoders which start and end at a known state. This trellis termination directly affects the performance of turbo codes.

Turbo NOC: a framework for the design of Network-on-Chip-basedturbo decoder architectures [PDF]
, 2010 This paper proposes a general framework for the design and simulation of network-on-chip-based turbo decoder architectures. Several parameters in the design space are investigated, namely, network topology, parallelism degree, the rate at which messages ...

Non-recursive max* operator with reduced implementation complexity for turbo decoding [PDF]
, 2012 In this study, the authors deal with the problem of how to effectively approximate the max?? operator when having n > 2 input values, with the aim of reducing implementation complexity of conventional Log-MAP turbo decoders.

Performance of convolutional interleavers with different spacing parameters in turbo codes [PDF]
, 2005 This paper considers application of a convolutional interleaver and the issue of infuence of the space parameter in the turbo code performance. Similarly to previously considered convolutional interleavers, the new interleavers are designed as block ...

Iterative decoding convergence and termination of serially concatenated codes [PDF]
, 2010 In this paper we demonstrate that previously proposed serially concatenated codes only facilitate iterative decoding convergence towards points that are near but not at the top-right hand corner of the EXIT chart, which typically results in an error ...

On interleaver design for serially concatenated convolutional codes [PDF]
Proceedings. 2001 IEEE International Symposium on Information Theory (IEEE Cat. No.01CH37252), 2002 Serially concatenated convolutional codes are considered. The free distance of this construction is shown to be lower-bounded by the product of the free distances of the outer and inner codes, if the precipices of the interleaver are sufficiently large. It is shown how to construct a convolutional scrambler with a given precipice.

New Code Matched Interleaver for Turbo Codes with Short Frames
Advances in Electrical and Computer Engineering, 2010 Turbo codes are a parallel concatenation of two or more convolutional codes, separated by interleavers, therefore their performance is not influenced just by the constituent encoders, but also by the interleaver.

Novel Analytical Results on Performance of Bit-Interleaved and Chip-Interleaved DS-CDMA With Convolutional Coding [PDF]
IEEE Transactions on Vehicular Technology, 2005 We present a unified performance analysis for the conventional bit-interleaved direct-sequence (DS) code-division multiple access (BIDS-CDMA) and the more recently proposed chip-interleaved DS-CDMA (CIDS-CDMA), both with channel coding. Simple CIDS-CDMA treats a set of bits at a time and interleaves their chips together for transmission.
