Abstract

This paper proposes a sub-channel partitioning based on adaptive allocation of Variable Length Codes (VLCs) with Unequal Error Protection (UEP) scheme for Orthogonal Frequency Division Multiplexing (OFDM) system. In this scheme, video data is partitioned into high-priority (HP) and low-priority (LP) coefficients according to the importance of the data, then it is allocated to sub-channels for transmission over OFDM system. A proposed technique is applied by interleaving the Resynchronization Markers between VLCs to isolate the propagation of error over video stream and completed by another technique to improve the performance of the video decoder decision at lower values of Signal to Interference Noise Ratio (SINR).
