Analisis Model Kanal SUI Berdasarkan Modulasi QAM dan Variasi Bandwidth
ABSTRACT: Wimax is the
wireless technology providing link of broadband in distance which far. Wimax is
technology of broadband having high speed access and the wide reach. Such as
system communications of previous nirkabel, wimax also have model of different
propagation. Propagation models of wimax involve variation of delay (μs), power
(dB), Factor K (dB), Doppler frequency (Hz). This Model called SUI (Stanford
University Interim) channel. Variation of Parameters SUI channel determine
performance of communications wimax. In this final project, analysed SUI
channel use simulation where parameter of SUI channel of variation into 6
condition of channel SUI - 1 up to SUI-6. While performance of channel
presented in comparison of graph of BER and Eb/No. For wimax communication used
type of IEEE 802.16d with digital modulation 16 QAM and 64 QAM, include the
variation of cylic prefix and bandwidth. Simulation test result show that
simulation of SUI channel with type of modulation 16 QAM with cylic prefix 1/8,
bandwidth 1.5MHz can repair almost entirety of performance SUI channel. Five
SUI channel show best performance when at gyration of Eb/No 5dB up to 15 dB.
While result of simulation SUI channel with type of modulation 16QAM with cylic
prefix 1/16, bandwidth 20MHz showing bad performance, when improvement Eb/No of
gyration BER between 10-1 dan 100 for channel SUI-2, SUI-3, SUI-4, SUI-5,
SUI-6. Result of simulation SUI channel with type of modulation 64 QAM with
cylic prefix 1/8, bandwidth 1.5MHz showing best performance. Result of simulation
SUI channel with type of modulation 64 QAM with cylic prefix 1/16, bandwidth
20MHz showing bad performance.
