Convolutional interleaving for digital radio communications

Proceedings of 2nd IEEE International Conference on Universal Personal Communications, 2002
Interleaving 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, 1998
This 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, 1988
The 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.

Interleaver Design for Serially Concatenated Convolutional Codes: Theory and Application

IEEE Transactions on Information Theory, 2004
This paper addresses the problem of interleaver design for serially concatenated convolutional codes (SCCCs) tailored to the constituent codes of the SCCC configuration. We present a theoretical framework for interleaver optimization based on a cost function closely tied to the asymptotic bit-error rate (BER) of the block code C/sub s/ resulting from ...

Application of Bit Interleaving to Convolutional Codes for Short Packet Transmission

2019 IEEE International Conference on Industrial Cyber Physical Systems (ICPS), 2019
In 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.

Adaptive interleaver based on rate-compatible punctured convolutional codes

IEEE Transactions on Communications, 2009
This letter focuses on the design of an adaptive bit-interleaved coded modulation (BICM) scheme for frequency selective slow fading channels where the transmitter has certain knowledge of the channel response. In particular, we consider the design of the interleaver stage for a specific convolutional code operating with OFDM modulation.

Interleaved group convolutions for multitemporal multisensor crop classification

Infrared Physics & Technology, 2019
Abstract The multitemporal observation capability of remote sensing satellites is of increasing importance in crop monitoring. Nowadays we can obtain dense multitemporal data more easily because more and more Earth observation satellites are put into use.

Performance of Convolutional Codes With Finite-Depth Interleaving and Noisy Channel Estimates

IEEE Transactions on Communications, 2006
In 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 ...

Convolutional codes and finite interleavers for the block erasure channel

1994
In 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 ...
