Flat Fading Modeling in Fixed Microwave Radio Links Based on ITU-R P. 530-11

This paper mainly discusses the ITU-R P.530 flat fading model in fixed wireless channels. This empirical model introduces a more precise model than the traditional models. To evaluate the effect of this model on the system performance, the PDF of this flat fading model has been derived and used in the Monte Carlo simulation. According to the simulation results, the behavior of ITU-R P.530 model is significantly different from the lognormal model used conventionally in fixed wireless channel modeling, so using the lognormal distribution drastically causes to overestimate or underestimate the system power and fade margin in fixed wireless systems.
