Weight distribution of turbo codes with convolutional interleavers
IET Communications, 2007 A simple algorithm for the weight calculation of turbo codes with convolutional interleavers is presented. For codes with short interleaver lengths, the weight distributions are computed using conventionally proposed methods and then utilised together with the interleaver properties to determine the weight specifications for the code with a longer ...

On The Performance of Turbo Codes With Convolutional Interleavers [PDF]
2005 Asia-Pacific Conference on Communications, 2005 In this paper, some issues governing the block-wise performance of convolutional interleavers used in turbo codes are presented. Two different constructions of convolutional interleaver differing by the position of stuff bits in the interleaved data block are considered here. The performance assessment is based on the contribution of each weight to the

, 1997 An interleaver is a hardware device commonly used in conjunction with error correcting codes to counteract the effect of burst errors. Interleavers are in widespread use and much is known about them from an engineering standpoint.

On interleaved, differentially encoded convolutional codes [PDF]
IEEE Transactions on Information Theory, 1999 Summary: We study a serially interleaved concatenated code construction, where the outer code is a standard convolutional code, and the inner code is a recursive convolutional code of rate 1. We focus on the ubiquitous inner differential encoder (used, in particular, to resolve phase ambiguities), double differential encoder (used to resolve both phase

Evolutionary Algorithm Aided Interleaver Design for Serially Concatenated Codes [PDF]
, 2011 In this paper, we propose an algorithm for designing the interleavers of Serially Concatenated Codes (SCCs), in order to increase the Minimum Hamming Distance (MHD) between the legitimate permutations of the encoded bit sequence and hence to improve the ...

Interleaved Convolutional Code and Its Viterbi Decoder Architecture [PDF]
EURASIP Journal on Advances in Signal Processing, 2003 Summary: We propose an area-efficient high-speed interleaved Viterbi decoder architecture, which is based on the state-parallel architecture with register exchange path memory structure, for the interleaved convolutional code. The state-parallel architecture uses as many add-compare-select (ACS) units as the number of trellis states.

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 ...
