Analysis and Simulation of the Transmission Distortions of the Mobile Digital Television DVB-SH Part 2: Satellite Mode DVB-SH-B with TDM; Part 2: Satellite Mode DVB-SH-B with TDM

Abstract

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. Finally, achieved results are evaluated and clearly discussed.
