QoS Performance Analysis of Video Conferencing Over Wimax using different Modulation Schemes

ENSC 427 - COMMUNICATION NETWORKS Analysis of Quality of Service (QoS) for Video Conferencing in WiMAX Networks

Performance Evaluation of Different Modulation Techniques for Different Mobility Pattern by using SVC Code over Wimax

Wimax is Wireless Interoperability for Microwave Access for Wireless Communication IEEE 802. 16e. In this paper the performance of different modulation techniques (QAM, adaptive and QPSK) by using different mobility patterns for VOD over Wimax with the help of VOD SVC coding. The work is done in terms of throughput, traffic sent and traffic received using OPNET modeler 14. 5. Simulation shows t...

A Performance Analysis of Different Scheduling Schemes in WiMAX

IEEE 802.16 (WiMAX) aims to present high speed wireless access to cover wide range coverage. The base station (BS) and the subscriber station (SS) are the main parts of WiMAX. WiMAX uses either Point-to-Multipoint (PMP) or mesh topologies. In the PMP mode, the SSs connect to the BS to gain access to the network. However, in the mesh mode, the SSs connect to each other to gain access to the BS. ...

BER Performance Analysis of MRC for OFDM System using Different Modulation Schemes over Rayleigh Fading Channel

In wireless communication systems antenna diversity is an important technique to combat multipath effects of fading to improve the system performance and to increase the channel capacity. This paper explores receiving antenna diversity issues for Orthogonal Frequency Division Multiplexing (OFDM) in Rayleigh fading environment using maximal ratio combining (MRC). The performance of MRC for OFDM ...
