Introduction: The problem of compressed pattern matching deals with ways to find a pattern within a compressed file, without decompressing it first. The techniques for solving this problem fall into two major categories – creating a unique compression scheme that enables efficient pattern matching; or using some known compression scheme and develop algorithms to search the files it produces. In...

In order to improve coding efficiency in the scalable extension of H.264/AVC, an inter-layer prediction mechanism is incorporated. This exploits as much lower layer information as possible to inform the process of coding the enhancement layer(s). However it also greatly increases the computational complexity. In this paper, a fast mode decision algorithm for efficient implementation of the SVC ...

Adapting the transmission rate in an LMS channel is a challenging task because of the relatively fast time variations, of the long delays involved, and of the difficulty in mapping the parameters of a time-varying channel into communication performance. In this paper, we propose two strategies for dealing with these impairments, namely, multi-layer coding (MLC) in the forward link, and open-loo...

Visible light communications (VLC) is a good candidate technology for the 6th generation (6G) wireless communications. Red, green, and blue (RGB) light-emitting diodes (LEDs) based VLC has become an important research branch due to its low price high reliability. However, saturation of photodiode (PD) caused by ambient background may seriously degrade bit error rate (BER) performance RGB-VLC sy...
