This paper deals with the examination of the transmission distortions of the latest digital TV standards DVB-H (Digital Video Broadcasting to Handhelds) and DVB-SH (Satellite to Handhelds) in portable and mobile TV over fading channels. These channel model profiles respect Dopplers shift, which is occur thank to the movement of the receiver. For the compari-son of the transmission distortions in DVB-H/SH-A in mentioned channel models an appropriate application was developed in MATLAB. Simulation results of the BER (Bit Error Ratio) after Viterbi decoding (DVB-H), after turbo decoding (DVB-SH-A) and MER (Modulation Error Ratio) on C/N (Carrier-to Noise Ratio) for QPSK and 16QAM modulations were obtained, compared and evaluated. Moreover, typical results and the examples or illustration constellation diagrams for the various transmission scenarios and channel types are also presented. Finally, achieved results are evaluated and clearly discussed.
