Digital Video Broadcasting Terrestrial(DVBT) Simulink Design & Channel Performance Analysis for BER & PSNR
The demand of wireless communication is growing exponentially and next generation of wireless broadband multimedia communication systems will integrate various function and application in same system which supports large data rates with sufficient robustness to radio channel impairments, requires careful choosing of modulation technique. The suitable choice is orthogonal frequency division multiplexing (OFDM) which is special case of multi-carrier communication system, where single data stream is transmitted over number of lower sub-carrier. This altogether has brought to the conclusion that one radio frequency channel can be used to transmit more than one TV program. Digital video broadcasting (DVB-T) means broadcasting a multiplex, a package of various services. We had implemented DVBT system with addition to an effective scheme called as Orthogonal Frequency Division Multiplexing (OFDM) with which the high bit rate over the frequency selective channel is guaranteed to some extent.

Matlab Basics and Image Processing
MATLAB (matrix laboratory) is a numerical computing environment and fourth-generation programming language. Developed by Math Works, MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages, including C, C++, Java, and Fortran. MATLAB is widely used in all areas of applied mathematics, in education and research at universities, and in the industry. Image processing usually refers to digital image processing, but optical and analog also are possible. image processing is any form of signal processing for which the input is an image, such as a photograph or video frame; the output of image processing may be either an image or a set of characteristics or parameters related to the image. MATLAB allows you to deal easily with images and videao, audio then any other software. Algorithm development is central to image processing and computer vision because each situa

MATLAB is widely used in all areas of applied mathematics, in education and research at universities, and in the industry. It is preferred over other languages because of its advantages as: Its basic data element is the matrix. Several mathematical operations that work on arrays or matrices are built-in to the Matlab environment. Adding two arrays together needs only one command, instead of a for or while loop. The graphical output is optimized for interaction. You can plot your data very easily, and then change colors, sizes, scales, etc, by using the graphical interactive tools. Matlab’s functionality can be greatly expanded by the ad
