Abstract AR
In this work Hata, Lee, Walfisch-Ikegami and Free Space Loss models have been compared with practical path loss based on series of measurements in Karada district in Baghdad for GSM900 downlink band.
Hata model showed the closest path loss predictions with mean square error = 10.8 dB, but these results are far from good prediction results and need enhancement.
Hata model was optimized using Least Squares method based on measured received signal power.
The optimized Hata model showed much better results from the original Hata with mean square error = 6.96 dB.
The simulation and calculations were implemented using MATLAB R2009b.
The measurements were done using Field Test Display (FTD) with a compatible hand phone to measure signal strength.
A Ground Positioning System (GPS) was used to measure the distance from transmitter
