Performance Evaluation Internet Protocol Television (IPTV) by Taking Various Modulation Schemes
IEEE describes various modulation mechanisms for WiMAX i.e. QPSK, BPSK, 16 QAM and 64 QAM. This paper measures the performance of Internet Protocol TeleVision (IPTV) over Fixed WiMAX system taking various combinations of digital modulation. The performance is analyzed considering a number of main system parameters which involve the variation in the path-loss, video coding, scheduling service classes, various rated codes in FEC channel coding. The performance evaluation was carried out by utilizing OPNET simulator.
