Abstract
The most commonly used transmission channel in nowadays provides the same level of protection for all the information symbols. As the level of protection should be adequate to the importance of the information set, it is justified to use UEP channels in order to protect information of variable importance. Multiresolution channel decomposition has emerged as a strong concept and when combined with H.264/AVC layered multiresolution source it leads to outstanding results especially for mobile TV applications. Our approach is a double multiresolution scheme with embedded constellation modulations on its baseband channels followed by OFDM time/frequency multiresolution passband modulation. The aim is to protect The NAL units carrying the most valuable information by the coarse constellations into coarse sub-channels, and the NAL units that contain residual data by fined constellations and transposed into the fined OFDM sub-channels. In the multiresolution protection coding, our approach is a multiresolution decomposition of the core convolutional constituent of the PCCC where the NAL units carrying the most valuable information are coded by the rugged coefficient of the multiresolution code and the NAL units that contains residual data are coded by refined less secure coding coefficients.
Highlights
While Shannon theory for the separation of source coding from channel coding hold only for point to point communication system [1]
First we investigate the VCL and the network abstraction layer (NAL) of the H.264/AVC for a partitioning of data, our aim is to extract the features of VCL and NAL according to their importance
We discuss its bound performance and we generaze for the multilevel multiresolution codeword decomposition system, we present a simulation comparison with conventional single resolution Turbo code for H.264/AVC UEP application
Summary
