Abstract:
In this paper, the authors propose a new steganographic scheme based on vector quantisation (VQ) andsearch-order coding (SOC).The capacity of the proposed scheme is higher than others based on VQand the quality ofstego-image is acceptive. In general, the capacity of the schemes based on VQ is usually 1-bit per block. In 2004, Yuet al. proposed a scheme to increase the capacity to 3-bit per pair of blocks. In the proposed scheme, the authorsutilised multiple codebooks and chose the combinations of per pair of blocks, to embed ....etc

Abstract

Designing a system able to cope with a hostile channel is a typical challenge for data communication Engineers. High- data- rate communication over power lines is an exemplar case: while power lines are potentially convenient and in expensive “no new wire” medium for data transmission their features make it very difficult to design a simple modem. This paper illustrates main features of hostile channel, and some of the solution advocated for modem design. ....etc

ABSTRACT
There is a need to select the 'first step up' modulation scheme for higher data rate frequency hopping systems. This is seen as one step in a longer journey where considerably higher data rates are used. In order to make this progression viable, the first step should be taken with a well proven modulation scheme. An ....etc

A New Bit-Allocation Scheme for Coding of Digital Audio Using Psychoacoustic Modeling

Abstract:
In this paper we present a modified adaptive bit-allocation scheme for coding of audio signals using psychoacoustic modeling. Statistical redundancy reduction (lossless coding) generally gives compression ratios up to 2. We increase this ratio using perceptual irrelevancy removal (lossy coding). In this work MPEG-1 Layer-1 standard for psychoacoustic modeling is used and compression is improved by modifying the bit-allocation ....etc
