Analytical performance of digital terrestrial television transmitter stations for mobile broadcasting using ISDB-T standard over AWGN and fading channel

Abstract:

This project presents the analysis and performance evaluation for digital terrestrial television transmitter stations for mobile broadcasting using ISDB-T standard over AWGN and fading channel. A main broadcast transmitter with a secondary transmitter has been evaluated. The second station works with a lower power regarding the main broadcast transmitter, for this project with a 100:1 ratio. Under this scenario, two working options has been defined: (i) both stations transmit the same information, where the secondary station was considered as a repeater station, and (ii) both stations transmit different information, building an environment of co-channel interference. The performance by the bit error rate as a function of the receiver location was presented. The simulation and theoretical results show the improvement or deterioration of the signal, respectively to the working options stablished for the ISDB-T standard's A layer in order to validate repeater stations for digital terrestrial television mobile broadcasting.
