Abstract
A method is presented for evaluating dual diversity receivig systems by relating the characteristics of the receiving equipment to the signal levels at both receiving antennas. The characteristics of the receiving equipment are described by relating the quality of the output traffic to the input signal level. The input signal levels are in turn described in terms of the bivariate Rayleigh probability distribution function. The method is sufficiently general to enable extension to evaluate triple diversity systems and is independent of the frequency range over which diversity fading phenomena occur. The method can also be simplified to examine the over-all effectiveness of a nondiversity receiving system.
