Combinatorial joint source-channel coding
Traditional error correction and source coding has focused on the stochastic setting where separation based schemes are optimal, and current solutions for applications requiring both lossy compression and noise resilience reflect this approach. However, in the adversarial setting, with worst case …

Channel coding for high speed links
This thesis explores the benefit of channel coding for high-speed backplane or chip-to-chip interconnects, referred to as the high-speed links. Although both power-constrained and bandwidth-limited, the high-speed links need to support data rates in the Gbps range at low error probabilities. …

Source and Channel Coding for Wireless Networks
… we study the problem of distributed source coding. Distributed source coding refers to the compression of correlated sources by encoders that are physically separated. The pioneering result of Slepian and Wolf states that the rate region for the lossless distributed source coding problem is …

Joint source channel coding for progressive image transmission
… those embedded bit streams are very sensitive to channel noise and protections from channel coding are necessary. Typical error correcting capability of channel codes varies according to different channel conditions. Thus, separate design leads to performance degradation relative to what could be …

NEW PARADIGMS IN SOURCE CODING AND CHANNEL CODING
… of information theory, data compression and channel coding, are often considered as having reached maturity a long time ago. Our research brings fresh perspectives to both these areas by challenging long-standing assumptions and introducing new frameworks. The Shannon entropy and …

Source and Channel Coding of Images for Noisy Channels
… are explored in the context of erasure channels. The erasure channel can be considered an abstraction of an arbitrary physical channel as long as reliable error detection is possible, so the methods are broadly applicable. A multistage coding structure is proposed which offers much …

Characterization and Computation of Optimal Distributions for Channel Coding
… QAM schemes at all transmission rate below the channel capacity.

Dynamic information and constraints in source and channel coding
This thesis explore dynamics in source coding and channel coding. We begin by introducing the idea of distortion side information, which does not directly depend on the source but instead affects the distortion measure. Such distortion side information is not only useful at the encoder but under …

Signal Processing for Joint Source -Channel Coding of Digital Images
… the data into binary representation and then channel coding it to recover from transmission errors, this thesis advocates the joint source-channel coding solution to the problem. The joint approach potentially leads to significant performance gains in emerging multiuser communication scenarios …

A comparison of two novel channel coding techniques for CDMA
… to improve system capacity. Several alternative coding techniques are available, including "trellis codes" specifically designed for CDMA, very low rate convolutional codes and conventional convolutional codes. An analytic approach is developed to compare the performance of different coding …

ARQ protocol for joint source and channel coding and its applications
… theorem states that for transmission over noisy channels, approaching channel capacity is possible with the separation of source and channel coding. Practically, the situation is different. Infinite size blocks are needed to achieve this theoretical limit. Also, time-varying channels require a …

Source-channel coding for coordination over a noisy two-node network
… aim of this study is to examine Shannon’s source-channel separation theorem in the context of coordination. To that end, a general joint scheme to achieve the strong notion of coordination over a discrete memoryless channel is introduced. The strong coordination notion requires that the L_1 …

Source and channel coding for low-bandwidth speech communication between optoelectronic devices
… this thesis focuses on the source and coding techniques used for an optical communication system. A freeware linear predictive vocoder developed by Speex was eventually adopted to compress speech to the bandwidth of the optoelectronic fibers. Several channel coding techniques were …

Empirical rate-distortion study of compressive sensing-based joint source-channel coding
… uses compressive sensing (CS) as joint source-channel coding. We investigate the rate-distortion behavior of both point-to-point and distributed cases. First, we propose an efficient algorithm to find the 4-norm regularization parameter that is required by the Least Absolute Shrinkage and …
