The objective of this paper is to analyze the performance of WiMAX Communication Model by implementing Stamford University Interim(SUI)-1 and Stamford University Interim(SUI)-2 communication channel. We evaluated the performance of WiMAX Physical layer by implementing wavelet in w, under different combination of digital modulation techniques (16-PSK, QAM and 16-QAM) over SUI 1 and SUI 2 Communication Channels. | International Journal of Computer Networks and Communications Security VOL. 5, NO. 8, AUGUST 2017, 165–170 Available online at: E-ISSN 2308-9830 (Online) / ISSN 2410-0595 (Print) Performance Comparison of SUI communication channel with Wavelet implemented WiMAX Communication System RIDWAN UL ISLAM1, ISLAM2, FARHANA ENAM3 and HALIDA HOMYARA4 1 2 Lecturer, Dept. of CSE, EXIM Bank Agricultural University, Chapainowabgong, Bangladesh Lecturer, Dept. of CSE, Atish Dipankar University of Science & Technology, Dhaka, Bangladesh 3, 4 Associate Professor, Dept of ICE, Rajshahi University, Rajshahi, Bangladesh. 1 ABSTRACT The objective of this paper is to analyze the performance of WiMAX Communication Model by implementing Stamford University Interim(SUI)-1 and Stamford University Interim(SUI)-2 communication channel. We evaluated the performance of WiMAX Physical layer by implementing wavelet in place of IFFT, under different combination of digital modulation techniques (16-PSK, QAM and 16-QAM) over SUI 1 and SUI 2 Communication Channels. In our research work, we investigated the physical layer performance on the basis of bit error rate (BER) and signal to noise ratio (SNR). The simulation results of estimated Bit Error Rate (BER) displays that the implementation of wavelet transformation is highly effective against the implementation of FFT transformation. The simulation results also showed that WiMAX system that use SUI-2 Channel had Significantly less Bit Error Rate then the Model using SUI-1 Channel.

The huge uptake rate of mobile phone technology, Wireless Local Area Networks (WLAN) and the exponential growth of the Internet has resulted in an increased demand for new methods of obtaining high capacity wireless networks.
