Analysis of propagation model in conformance with IEEE 802.16-2009-based fixed wireless networks

Abstract

This work presents a performance analysis among different propagation models to estimate path loss on the wireless channel for communication systems in conformance with IEEE 802.16-2009 WirelessMAN Fixed OFDM. We developed and implemented a simulator using Matlab®, this simulator considers the channel losses and reflects their effects on the physical layer. The system implementation considers different types of modulations and coding rates defined in the standard. The program allows obtaining results about path loss, transmitting power as a function of BER, and transmitting power as a function of Eb/No. The channel considers losses produced by the wireless medium with shadowing, and an AWGN channel described by a standard deviation obtained from the Eb/No produced by the transmit power. We compared Yon Soo Cho, SUI and Free Space models at 3.5 GHz to obtain the bit error probability. We determined Yon Soo Cho model shows better results for rural areas than SUI model.
