Performance Evaluation of Voice and video conferencing For WIMAX Network under Various Modulation techniques
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2016, Vol 18, Issue 4
Abstract
Abstract: Worldwide interoperability for Microwave Access (WIMAX) that based on 802.16d/e Orthogonal Frequency Division Multiplexing (OFDM) and based on adaptive Physical Layer (PHY), It provides wireless broadband to fixed and mobile terminals, The basic WIMAX feature is wireless transmission infrastructure which allows a fast use as well as low maintenance costs, Modulation techniques enable WIMAX network to be optimized. WIMAX supports BPSK, 16-QAM, DPSK, and 64-QAM as a modulation technique. This paper present evaluation of various modulation techniques and study of performance for voice and video conferencing applications, An Opnet software used to simulate WIMAX Modulation techniques impact on voice and video conferencing, The simulation results includes the performance analysis for bit error rate (BER), SNR, MOS, MOS loss Rate, end to end packet delay and Jitter of different modulation.
