摘要

The problems being experienced by video conferencing are voice and video packet end-to-end delay, video packets delay, and throughput Worldwide Interoperability for Microwave Access (WIMAX) comes into use as subscribers demand for better quality of service in the area of voice and video multimedia applications with high-speed data connection, excetient security and mobility. There is a great need to show improvements in modulation scheme with respect to packet end-to-end delay, throughput and packet delay variation performance metrics. Hence, a quantitative approach was developed using the Optimized Network Engineering Tool (OPNET) Modeler to show improvements in modulation scheme for the performance of video conference multimedia application over the WIMAX technology with respect to several performance metrics. The results obtained shows that packet end-to-end delay, throughput issues and packet delay variation issues that have right modulation .scheme better .suited for each issue. For all delays, the QPSK1/2 is noted to be steady, having less delays and interruptions. Hence, this particular quadrature amplitude modulation scheme is better for use when compared to the 16 QAM 1/2 and 64 QAM 1/2 with respect to the need to have shorter delays. Whereas for throughput, data transferred over a specific period of time in 16 QAM 1/2 is better than the 64 QAM 1/2 or QPSK 1/2.
