Abstract :
We analyze the error performance of coherent binary keying with optimum combining in interference and noise using the joint probability density function of the eigenvalues of the interference correlation matrix. A flat Rayleigh fading environment with space diversity, equipower interferers, and additive white Gaussian noise is considered. Let L denote the diversity order and N the number of interferers. The interference correlation matrix follows a Wishart distribution when N≥L, and a pseudo-Wishart distribution when N\n\n\t\t
