Book Description :

Distributed source coding (DSC) refers to the problem of compressing two or more physically-separated information sources, where the sources (e.g. sensors) send the (compressed) information to a central point (e.g. a monitoring station) without communicating to each other. Cooperative communication, also known as user cooperation or the relay channel problem, allows single-antenna users in a multi-user scenario to share antennas with each other to form a virtual multiple-antenna system. These two technologies, originated in the seventies, have caused a resurgence of interest in recent years. In this dissertation, we investigate these two technologies and try to apply distributed source coding into user cooperation. Three topics are studied: The first is to develop a new scheme to attack the noisy-channel Slepian-Wolf coding problem using serially concatenated codes (SCC). The advantage is two-fold: (i) separate refining of compression rate and error protection capability is made possible and (ii) many useful results about SCC can be used to achieve joint optimization. The second topic considers the design of two-user cooperation schemes by exploiting distributed source coding technologies. Two user cooperation schemes, Slepian-Wolf cooperation and Wyner-Ziv cooperation, are proposed, which exploit Slepian-Wolf coding and Wyner-Ziv coding, respectively. Possibly the first practical schemes that implement the idea of compress-and-forward, these schemes offer substantial gains over existing cooperative strategies especially when the inter-user channel is at outage. The third topic is to develop an extension for cooperative communication to High-Speed Packet Downlink Access (HSDPA) cellular system which increases both the overall cell capacity as well as coverage near the cell edge at a relatively low cost.

Book Description :

Distributed source coding, the separate encoding and joint decoding of statistically dependent sources, has many potential applications ranging from lower complexity capsule endoscopy to higher throughput satellite imaging. This dissertation improves distributed source coding algorithms and the analysis of their coding performance to handle uncertainty in the statistical dependence among sources. We construct sequences of rate-adaptive low-density parity-check (LDPC) codes that enable encoders to switch flexibly among coding rates in order to adapt to arbitrary degrees of statistical dependence. These code sequences operate close to the Slepian-Wolf bound at all rates. Rate-adaptive LDPC codes with well-designed source degree distributions outperform commonly used rate-adaptive turbo codes. We then consider distributed source coding in the presence of hidden variables that parameterize the statistical dependence among sources. We derive performance bounds for binary and multilevel models of this problem and devise coding algorithms for both cases. Each encoder sends some portion of its source to the decoder uncoded as doping bits. The decoder uses the sum-product algorithm to simultaneously recover the source and the hidden statistical dependence variables. This system performs close to the derived bounds when an appropriate doping rate is selected. We concurrently develop techniques based on density evolution to analyze our coding algorithms. Experiments show that our models closely approximate empirical coding performance. This property allows us to efficiently optimize parameters of the algorithms, such as source degree distributions and doping rates. We finally demonstrate the application of these adaptive distributed source coding techniques to reduced-reference video quality monitoring, multiview coding and low-complexity video encoding.

Book Description :

Experimental results for Wyner-Ziv quantization of Gaussian sources show consistency between the rate-distortion performance of the quantizers found by our extension of the Lloyd algorithm, and the performance predicted by the high-rate theory presented. Implementations of distributed transform codecs of clean Gaussian data and noisy images experimentally support the rate-distortion improvement due to the introduction of the discrete cosine transform, predicted in the theory developed.

Book Description :

Conventional multimedia compression leverages the source statistics at the encoder side. This is not suitable for some emerging applications such as wireless sensor networks, where the encoders usually have limited functionalities and power supplies, therefore it is desired to shift the bulk of computational burden to the decoder side. The resulting new coding paradigm is called distributed source coding (DSC). Most practical DSC schemes only achieve good results when a priori knowledge about the source statistics is assumed. For DSC of real-world sources such as images and videos, such knowledge is not really available. In this dissertation, we focus on designing decoder-side learning schemes for better understanding of the source statistics, based on which practical DSC systems can be built for high-efficiency, low-cost, and secure multimedia communications. We have studied distributed video coding and compression of encrypted images and videos. We propose to enable partial access to the current source through progressive decoding, such that the decoder's knowledge about the source statistics can be progressively refined. The resulting schemes have achieved significant improvement in coding efficiency. We also studied the rate allocation problem to optimize the power consumption in transmitting multiple correlated sources over a wireless sensor network. The framework developed in this dissertation will provide significant insights and become important building blocks in distributed video applications, including those that are of significant importance to the national security, agriculture, economy, and healthcare.
