WiMAX (Worldwide interoperability for micro wave access<br>technology) is a technology based on IEEE 802.16 standard, which provides broadband service for fixed and mobile users<br>over long distances at high speed. Modulation and coding is one of the features of PHY layer which is used to load the data<br>in the uplink and downlink during transmission. The existing system selects the MCS based on the channel<br>quality.Modulation and coding scheme can also be selected based on the type of traffic used. This paper focuses on the<br>physical layer design aspect namely modulation and coding scheme(MCS) for the VOIP traffic over WiMAX. The<br>simulation is done for fixed WiMAX environment. Throughput and packet delay is taken as the main parameter for<br>evaluating the performance of WiMAX. This paper focuses on selecting appropriate Modulation and encoding scheme over<br>the WiMAX network for the voice and video application.</p> ER -
