Abstract:
In this thesis, we investigate the zero-delay transmission of source samples over three different types of communication channel models. First, we consider the zero-delay transmission of a Gaussian source sample over an additive white Gaussian noise (AWGN) channel in the presence of an additive white Gaussian (AWG) interference, which is fully known by the transmitter. We propose three parameterized linear and non-linear transmission schemes for this scenario, and compare the corresponding mean square error (MSE) performances with that of a numerically optimized encoder, obtained using the nec

CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO<br>Este trabalho estuda o problema de compressão de imagens de sensoriamento remoto segundo a ótica da codificação conjunta fonte-canal. É analisado o desempenho de métodos baseados em quantização vetorial segundo o algoritmo LBG, principalmente o COVQ (Channel Optimized Vector Quantizer) bem como a quantização vetorial estruturada em árvore. Dentro desse contexto, são propostos 2 novos métodos para a resolução do problema: (1)Uma quantização vetorial estruturada em árvores que leva em conta a transmissão através de canais

Abstract:
<p>In this dissertation, we explore the possibility of transmitting discrete-time, continuous amplitude sources over discrete-time, continuous-amplitude channels by using non-linear direct source-channel mappings. This is a joint source-channel coding technique where there is no real distinction between the source coding part and the channel coding part. In contrast to traditional digital communication systems, these techniques are only suited for transmitting sources which tolerate a certain amount of distortion, e.g. images and sound. The reason for this restriction is that the channel noise

Abstract:
Shannon's separate source and channel coding theorem suggests that communication of throughputs closely approaching the capacity of the channel can be achieved using an near-entropy source code to compress a source by removing all redundancy, combined with a near-capacity channel code which adds redundancy to increase the resilience to transmission errors. However, in practice, Separate Source and Channel Coding (SSCC) can impose excessive delay and complexity, or cannot tolerate any transmission errors without causing an endless cascade of errors. This motives Joint Source and Channel Coding
