Multiresolution Joint Source-Channel Coding for Wireless Channels

Non Linear Joint Source Channel Coding for Broadcast Channels

A novel Joint Source Channel Scheme for the two user Gaussian Broadcast channel is developed here. The scheme transmits a Bivariate Gaussian Source over a Discrete Memoryless Additive White Gaussian Noise Channel. The scheme belongs to the family of codes termed Nested Quantization. The ultimate theoretical communication limits of the Gaussian Broadcast channel are given and the different codin...

Joint Source-Channel-Fountain Coding for Asynchronous Broadcast

A novel concept of joint source-fountain coding for asynchronous wireless broadcast is presented. The traditional field of joint source-channel coding aims in both lossless data compression as well as reliable data delivery. Besides, fountain coding allows reliable broadcast without the need of feedback, and furthermore, asynchronous data access, i.e., each receiver is able to decide when it wa...

A Subband Coding Method for HDTV

This paper introduces a new HDTV coder based on motion compensation, subband codling, and high order conditional entropy coding. The proposed coder exploits the temporal and spatial statistical dependencies inherent in the HDTV signal by using intraand inter-subband conditioning for coding both the motion coordinates and the residual signal. The new framework provides an easy way to control the...

Enhanced 8-VSB transmission for North-American HDTV terrestrial broadcast

We present a new robust backward compatible 8-VSB transmission system for HDTV terrestrial broadcast. The new transmission system allows better reception of signals for portable, mobile and indoor receivers. In the proposed system a scalable fraction of the main service is used to transmit robustly encoded data. The robust service has at least a 6 dB fade margin advantage over the main service....
