MODELING DIVERSITY RECEPTION OVER NARROW-BAND FIXED WIRELESS CHANNELS

A complete first-order statistical characterisation of two-branch dive rsity reception over narrowband fixed wireless channels can be given i n terms of just five channel parameters: the average path gains and Ri cean K-factors for each branch and the complex envelope correlation co efficient between the time-varying parts of the mio path gains. Propag ation measurements collected in typical suburban environments have sho wn that each of these parameters, or its logarithm is close to Gaussia n, Accordingly, the set may be cast as a five-element vector of jointl y random Gaussian processes which are completely specified by the mean s, standard deviations, and mutual correlation coefficients of the fiv e parameters.
