A complete first-order statistical characterization of two-branch diversity reception over narrowband fixed wireless channels can be given in terms of just five channel parameters: the average path gains and Ricean K-factors for each branch and the complex envelope correlation coefficient between the time-varying parts of the two path gains. Propagation measurements collected in typical suburban environments have shown that each of these parameters, or its logarithm, is close to Gaussian. Accordingly, the set may be cast as a five-element vector of jointly random Gaussian processes which are completely specified by the means, standard variations, and mutual correlation coefficients of the five parameters
