Abstract:
In the research, the theory of digital terrestrial television broadcasting and the details of the simulation model are provided. The tool used is a matlab editor to simulation. In the simulation model the parameter setting for digital modulation and demodulation, modulating a random signal, bit error rate analysis tool by using AWGN channel, model of digital video broadcasting- terrestrial to evaluate signal to noise ratio (SNR) and performance of M-QAM for varying M.
