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.

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 ...

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 ...

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 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.

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.

Interleaved convolutional coding for the turbulent atmospheric optical communication channel
IEEE Transactions on Communications, 1988The coding gain of a constraint-length-three, rate one-half convolutional code over a long clear-air atmospheric direct-detection optical communication channel using binary pulse-position modulation signalling is directly measured as a function of interleaving delay for both hard- and soft-decision Viterbi decoding.

Application of Bit Interleaving to Convolutional Codes for Short Packet Transmission
2019 IEEE International Conference on Industrial Cyber Physical Systems (ICPS), 2019In recent years, the demand for high reliability in industrial wireless communication has been increasing. To meet the strict requirement, many researchers have studied various bit interleaving coding schemes for long packet transmission in industrial wireless networks.

Performance of Convolutional Codes With Finite-Depth Interleaving and Noisy Channel Estimates
IEEE Transactions on Communications, 2006In this paper, we derive the Chernoff bound of the pairwise error probability (PEP) and the exact PEP of convolutional codes in a time-varying Rician fading channel. With the assumptions that the channel estimator is a finite impulse response filter and the interleaving depth is finite, we are able to investigate the estimation-diversity tradeoff ...
