ABSTRACT
In This Seminar An adaptive watermarking capacity analysis in the spatial domain and wavelet domain has to be present. The relationship between the watermarking capacity and the watermark detection error rate is also discussed. The discussion of watermark detection error rate will help us finding the ways to embed more watermark messages while keeping an acceptable detection error rate, it is useful for the design of the general algorithms of watermarking and detection. The watermarking system is analyzed based on the channel capacity ....etc

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted t ....etc

Introduction
With the improvements in semiconductors optical free space communication has become n attractive alternative to existing signal conducts as fibre or wireless (RF). It offers high data rates and is much less expensive than underground fibre. But there are a few restrictions, which may mean it remains an alternative. Many engineers are familiar with one of two successful existing technologies for data communication: (1) Guided wave (e.g. fibre optics) and (2) wireless free space communication (e.g. RF). Fibre optics offers extremely ....etc

Introduction

This report presents three main topics we investigated as part of a project to build a Booth encoded multiply/accumulate VLSI chip. The original scope of work included synthesizing VHDL code using the Mentor Graphics tools. Exemplar was the VHDL compiler. Leonardo Spectrum was the synthesizer. Since my team, which included Kevin Delaney, did not meet a Mosis deadline our chip funding was lost. Since we did not actually fabricate a chip, we cannot discuss the success of our results. Likewise, VHDL synthesis using the ....etc
