BER Analysis of DVB with Different Encoding and Interleaving Schemes

Abstract: Digital television broadcasting is present and future of television. With the advent of digital technology, digital audio and video compression and other advanced signal processing, it is possible to transmit and receive broadband data over co-axial cable and through satellite and terrestrial. Digital television is a telecommunication system for broadcasting and receiving moving picture and sound by means of digital signals, in contrast to analogue signals in analogue (traditional) Television. It uses digital encoded data convolute the data and transmit the data with OFDM. Modulation data, which is digitally compressed. DVB is a European digital television standard that uses different modulation techniques like, 16 QAM, 64 QAM. DVB uses Convolutional interleaver for different combination like 1/4, 1/3, 2/3, 3/4 with Reed solemn encoder.
