On the Parallelism of Convolutional Turbo Decoding and Interleaving Interference.
2006In forward error correction, convolutional turbo codes were introduced to increase error correction capability approaching the Shannon bound. Decoding of these codes, however, is an iterative process requiring high computation rate and latency. Thus, in order to achieve high throughput and to reduce latency, crucial in emerging digital communication ...

Convolutional interleaving for digital radio communications
Proceedings of 2nd IEEE International Conference on Universal Personal Communications, 2002Interleaving enhances the quality of digital transmission over the radio fading channel. This enhancement comes at the cost of introducing additional time-delay, memory space requirements, and system complexity. This paper describes commonly used interleaving techniques.

Interleaving for outer convolutional codes in DS-CDMA systems
IEEE Transactions on Communications, 2000Summary: The paper deals with coding for direct-sequence code-division multiple-access (DS-CDMA) channels. A novel method for interleaver design is introduced that significantly improves the probability of error on Gaussian multiple-access channels.

Interleaved Concatenations of Polar Codes With BCH and Convolutional Codes
IEEE Journal on Selected Areas in Communications, 2016We analyze interleaved concatenation schemes of polar codes with outer binary BCH codes and convolutional codes. We show that both BCH-polar and Conv-polar codes can have a frame error rate that decays exponentially with the code length for all rates up to capacity, which is a substantial improvement in the error exponent over stand-alone polar codes ...

An improved interleaver design technique for parallel concatenated convolutional codes
IEEE International Conference on Communications, 2003. ICC '03., 2004This paper is aimed at the problem of designing optimized interleavers for parallel concatenated convolutional codes (PCCC) that satisfy several requirements simultaneously: 1) designing interleavers tailored to the constituent codes of the PCCC; 2) improving the distance spectra of the resulting turbo codes which dominate their asymptotic performance;

Performance of the Viterbi algorithm for interleaved convolutional codes
IEEE Transactions on Vehicular Technology, 1998This paper presents a maximum-likelihood decoder for error-burst channels with a very efficient implementation. In particular, the encoder is formed of an interleaved convolutional code with generator polynomials of the type [g/sup (1)/(D/sup I/), g/sup (2)/(D/sup I/)] (for a rate 1/2 coder), where I may assume a very high integer value.

Viterbi decoder architecture for interleaved convolutional code
Conference Record of the Thirty-Sixth Asilomar Conference on Signals, Systems and Computers, 2002., 2003Sn area efficient high speed Veterbi decoder architecture, which is based on the state-parallel architecture with register exchange path memory structure, for interleaved convolutional code is proposed By replacing each delay (or storage) element in state metrics memory (or path metrics memory) and path memory (or survival memory) with I delays ...

Convolutional codes and finite interleavers for the block erasure channel
1994In this paper we analyze a simple model which attempts to describe the transmission of convolutionally encoded data over channels with memory using finite interleaving. The model could for example describe the performance of a slow frequency hopping system in which every frequency is either totally blocked or else noiseless, and in which interleaving ...
