Analysis and Simulation of the Transmission Distortions of the Mobile Digital Television DVB-SH

This paper deals with the second part of the latest digital TV standard DVB-SH (Digital Video Broadcasting - Satellite to Handhelds) with focus on utilization of its advantages for the next generation of mobile TV broadcasting. In the second part the simulation model of DVB-SH-B, which is using satellite configuration with TDM (Time Division Multiplexing) transmission mode, is presented. The work is especially focused on the description of TDM system configuration. Dependences of BER on C/N ratio for all used types of modulations are compared in the Gaussian (AWGN) channel, which is generally used in DVB-SH/S2 standards for exploring of the transmission distortions. Moreover, in case of QPSK modulation, the data transmission was explored in the Ricean fading channel.
