Abstract

The results of investigations concerning the characterization of the performance of quadrature amplitude modulation (QAM) digital radio in the presence of selective fading and additive noise are presented. The prediction of outage probability due to multipath fading is accomplished by using Rummler´s simplified three-path model. The three-path model for characterization of the transmission medium is described. The procedure of outage calculation is outlined. A mathematical model is defined that is used to calculate the error performance of QAM systems in the presence of intersymbol interference and additive noise. The results obtained by using both the method of signatures and Monte Carlo simulation are presented.<>
