Abstract :
Low-delay source-channel transmission over parallel fading channels is studied. In this scenario separate source and channel coding is in general highly suboptimal. A scheme based on hybrid digital/analog joint source-channel coding is therefore proposed, employing scalar quantization and polynomial-based analog bandwidth expansion. Simulations demonstrate substantial performance gains.
