According to forecasts, by 2018 the number of mobile phone subscribers worldwide could cross the four billion barrier. Mauritius is also witnessing a major growth in mobile subscriptions and the total number of mobile subscriptions was 1,533,600 in 2013. Recently, there has been a growing concern with regards to the energy consumption of mobile phones which(More)
Turbo coded 64-QAM systems have been adopted by standards such as CDMA-2000 and Long Term Evolution (LTE) to achieve high data rates. Although several techniques have been developed to improve the performance of Turbo coded QAM systems, combinations of these techniques to produce hybrids with better performances, have not been fully exploited.

Video compression standards such as H.264/AVC and H.265/HEVC are widely used in applications such as video conferencing, streaming and television broadcasting. These compression standards have been ubiquitously adopted due to their high compression performance as compared to previous standards. However, compressed video may suffer from severe degradation(More)
This paper proposes an enhanced framework for H.264 video transmission whereby prioritised delay constrained retransmissions and error concealment have been employed. With the prioritisation framework, the impact of all lost macroblocks on the reconstructed frame is first assessed and macroblocks with the highest impact are given higher priority to be(More)
In this paper we propose a new application of Unequal Error Protection (UEP), in which UEP is used to improve channel and source synchronisation for image transmission. The source coding strategy consists of a 2-D wavelet decomposition followed by quantization and Huffman coding. Source synchronization is achieved by inserting resynchronisation markers into(More)
