Abstract

In this research various channel propagation models of wireless communication systems were analysed. There are many types of propagation models that can minutely calculate the path loss in all types of terrain. Performance estimation of different propagation models was analysed using simulations. In the simulations the selected propagation models have been proposed at the operating frequency of 1800 MHz for different receiver antenna heights in urban and rural environments. Simulations were performed using MATLAB R2013b. The propagation models depend on location, frequency range and clutter type such as urban, suburban and countryside. It was noticed from the results of the path loss calculation for 2 m, 7 m and 14 m receiver antenna heights in urban environment that COST 231 (W-I) model showed the lowest path loss results (138 dB) as compared with the other models in urban environment. On the contrary, SUI model showed the highest path loss result (166 dB in 2 m receiver antenna height) as compared with the other models in the same environment.

Highlights

The losses that occurred between transmitter and receiver is known as propagation path loss
Path loss is a major factor in the analysis and design of wireless communication system
The path loss of channel propagation models is estimated by stratifying different receiver antenna heights 4 m, 7 m and 14 m with fixed transmitter antenna height 29 m

Summary

Introduction

The losses that occurred between transmitter and receiver is known as propagation path loss. Path loss is a major factor in the analysis and design of wireless communication system. Path loss normally includes propagation losses caused by the natural expansion of the radio wave propagation in free space. The paper is arranged as follows: In section 2. The simulation models and scenarios are presented. The simulation results are analysed, and the conclusions follow in the last section In section 4. , the simulation results are analysed, and the conclusions follow in the last section
