Theoretical reliability of dual GPS antennas over wireless fading channel

Because equal gain diversity does not require estimation of the channel fading amplitudes, it is often used in practical as reduced complexity alternative to the maximal ratio processing. This paper develops an exact formulation in order to investigate the performance of equal gain combining. The approach of this paper and its main contribution is to model the Gaussian channel of aircraft global positioning systems. The performance is interested in the exact outage probability of dual branch equal gain combining in wireless system in presence of co-channel interference. The more general scenario of unequal power co-channel interferer is also formulated and derived. As the results, the closed form solution of outage probability corresponds to a Rayleigh fading.
