Over the last few decades\, many state-of-the-art techniques have been develope d to address the problem of reliable transmissions over AWGN channel links in digital communications. These developments include both information-th eoretic studies and explicit source and channel coding/modulation schemes for practical purposes. As a result\, effective solutions have been devise d and the results can serve as the fundamental theory and practice behind many modern communication systems. While AWGN model is useful in providing an insight into the underlying behavior of communication systems\, it ign ores some other impairments which are prevalent in various communication e nvironments. For instance\, non-Gaussian impulsive interference caused und esirable impulse triggers in the form of random bursts that occur over sho rt durations severely affect the throughput and reliability of many modern communication systems\, including power line communications\, digital sub scriber lines\, cognitive radio\, urban and indoor wireless communications \, underwater acoustic communications and so on. Non-Gaussian interference is also observed in audio\, video\, and imaging systems. Despite many adv ancements\, channels under non-Gaussian interference are not fully underst ood\, from both an information-theoretic and a practical point of view.\n\ nThis talk shall provide an introduction on the well-established area of i nformation theory and coding for AWGN channels\, as well as emerging resea rch directions in information theory and coding for non-Gaussian channels. The talk is divided in two parts. In the first part\, I will introduce so me introductory materials on information theory and coding designs in AWGN channels. The main focus is on the Shannon capacity and evolution of erro r control coding from the simplest block codes such as Hamming codes to ne ar-Shannon limit coding schemes that have recently been invented. I also d iscuss the improvements of error control coding over AWGN channels during the last few decades\, with respect to both the error performance and the complexity issue. In the second part of the talk\, I will provide an overv iew of current research on information theory and coding for non-Gaussian and non-linear channels\, with particular attention paid to impulsive inte rference channels and channels with low-resolution output quantization. I will also discuss major open research issues and directions for future res earch on these channels.\n\nCo-sponsored by: UBC Okanagan\n\nSpeaker(s): D r.
