Abstract: In this paper the Performance of Digital Video Broadcasting-Terresrial(DVB-T) Transmission and reception part is undertaken.Any audio,video or image is taken as input and calculating the Bit Error Rate(BER) between transmitted and received image then we are analysing the performance of the system for different Signal To Noise Ratio(SNR) values. The system is analysed for different types of channels such as AWGN, Rayleigh and Rician channels. Finally a comparative study of the systems for different channel and SNR conditions is analysed. DVB-T is a system that makes use of the Orthogonal Frequency Division Multiplexing(OFDM) concept for the faster transmission and reception of the data. It also involves the error detection and correction techniques by the forward error correction techniques.
