Abstract

In a frequency selective channel for wireless applications, we provide a new resources allocation procedure that enables the transmission of scalable images in accordance with end-to-end Quality of Service (QoS) constraints. This scheme is based on an Unequal Error Protection (UEP) policy with the possible truncation of the source data layers (after the source coding stage) and an optimal use of the available resources for each layer (with local flattening over the channel portion). The proposed algorithm is applied to the transmission of JPEG- 2000 scalable images over an OFDM channel. We analyze the performance of our method in term of perceived quality and speed, and show better results than State-Of-The-Art UEP schemes.
