ABSTRACT

OFDM (Orthogonal Frequency Division Multiplexing) is a modulation and multiple access technique that has been explored for over 20 years. Only recently has it been finding its way into commercial communications systems. OFDM, or multitone modulation, is presently used in a number of commercial wired and wireless applications. In order for any mobile system to create a rich user experience, it must provide ubiquitous, fast and user-friendly connectivity. OFDM has several unique properties that make it especially well suited to handle ....etc

ABSTRACT
A Graphics Processing Unit (GPU) is a microprocessor that has been designed specifically for the processing of 3D graphics. The processor is built with integrated transform, lighting, triangle setup/clipping, and rendering engines, capable of handling millions of math-intensive processes per second. GPUs allow products such as desktop PCs, portable computers, and game consoles to process real-time 3D graphics that only a few years ago were only available on high-end workstations. Used primarily for 3-D applications, ....etc

CHAPTER 1
INTRODUCTION
1.1 INTRODUCTION TO COMPUTER GRAPHICS
As a software interface for graphics hardware, OpenGL's main purpose is to render two- and three-dimensional objects into a frame buffer. These objects are described as sequences of vertices (which define geometric objects) or pixels (which define images). OpenGL performs several processing steps on this data to convert it to pixels to form the final desired image in the frame buffer.
OpenGL presents a global view of how OpenGL works; it contains the fo ....etc

IMAGE ENHANCEMENT TECHNIQUES

SUBMITTED BY
INTRODUCTION
Image enhancement widely used in computer graphics.
It is the sub areas of image processing.
The principle objectives of image enhancement techniques is to process an image so that the result is more

suitable than the original image for a specific application .
METHODS FOR IMAGE ENHANCEMENT
Image enhancement techniques can be divided into two broad categories:

1.Spatial domain methods .
2 Frequency domain methods.
SPATIAL DOMAIN METHODS ....etc

INTRODUCTION:
THE PILEUP effect has been recognized as a limiting factor in performing gamma-ray spectrometry at high count rates .Pileup occurs when two or more events take place so close in time that the measurement system responds as if it is a single event. The pileup effect deteriorates the resolution of the energy spectrum. It can even result in the total mas ....etc

ABSTRACT
The term echo cancellation is used in telephony to describe the process of removing echo from a voice communication in order to improve voice quality on a telephone call. In addition to improving subjective quality, this process increases the capacity achieved through silence suppression by preventing echo from traveling across a network.



Two sources of echo have primary relevance in telephony:
acoustic echo and
hybrid echo.
Echo cancellation involves first recognizing the originally transmitted signal that re-appe ....etc
