Performance and Sensitivity Analysis of Path Loss Models for WiMAX Signals

www.niecdelhi.ac.in The paper depicts investigation related to path loss estimation and overall performance of both theoretical and experimental propagation models. Performance of propagation models namely, SUI, Okumara-Hata and COST-231 has been analyzed and compared with the experimental results obtained for frequency range of 2360-2390 MHz of WiMAX signals in different environments. The performance analysis of these models reveals that COST 231-Hata Model gives closest approximation to experimental data. Thereafter, sensitivity analysis of various parameters i.e., base station height, receiver antenna height, correction factor was done to demonstrate which parameter can be modified for optimization of COST 231-Hata Model
