Motivated by recent results in multiple description image coding over wireless networks, we propose a scheme for transmission of multiple descriptions through hybrid packet loss and additive white Gaussian noise channel. Each description is coded into multiple bitstreams by applying SPIHT coding on wavelet trees along spatial orientations and each stream is further compressed using arithmetic c...

This paper examines iterative decoding of a serial concatenated coding scheme consisting of an outer convolutional and an inner Walsh-Hadamard block code, and the scheme is applied for an OFDM-CDMA uplink transmission. New aspects arise because OFDM enables the iterative decoding structure to exploit time as well as frequency diversity of a mobile radio channel. To the authors knowledge, this i...

Iterative decoding is used to achieve backward compatible performance improvement in several existing systems. Concatenated coding and iterative decoding are first set up using composite mappings, so that various applications in digital communication and recording can be described in a concise and uniform manner. An ambiguity zone detection (AZD) based iterative decoder, operating on generalize...

This letter considers an iterative decoding algorithm for non-binary linear block codes in which erasure and error decoding is performed for input words given by the sums of a hard-decision received sequence and given test patterns. We have proposed a new selection method of test patterns for the iterative decoding algorithm. Simulation results have shown that the decoding algorithm with test p...

Decoding with feedback or iterative decoding is an eecient, low-complexity means for \informa-tion handover" in any parallel or serial concate-nated coding scheme and in related applications. Invented twenty years ago, it has recently been payed considerable attention in the context of \Turbo Codes". Iterative decoding has been jus-tiied intuitively, but many question remain and perhaps will re...

The ongoing wireless communication evolution offers improvements for industrial applications where traditional wireline solutions causes prohibitive problems in terms of cost and feasibility. Many of these new wireless applications are packet oriented and timecritical. The deadline dependent coding (DDC) communication protocol presented here is explicitly intended for wireless real-time applica...

We propose an analysis tool of the finite-length iterative turbo decoding algorithm. The proposed tool is a generalized EXIT chart based on the mutual information transfer characteristics of the extrinsic information in the iterative turbo decoding algorithm. The proposed tool can describe the probabilistic convergence behavior of the iterative decoding algorithm. By using this tool, we obtain ...
