Performance of GMSK in frequency selective Rayleigh fadhi

The two-ray Rayleigh fading model accounts for the frequency selective fading experienced by the received signals in some digital cellular systems. For such fading channels, binary error probabilities of GNISK with discriminator detection or differential detection are considered in the presence of multiple, Rayleigh-faded, independent, cochannel interferers. The paper drives an exact solution for the average error probability and a near-exact but less computationally intensive solution. The near-exact solution is virtually indistinguishable from the exact solution for large carrier-to-interference ratios (CIR,. To establish the accuracy of the results, numerical examples are given.
