Abstract

We derive a closed form expression of the symbol error probability (SEP) for coherent detection of M-ary PSK signals using an array of antennas with optimum (or, equivalently, linear MMSE) combining in the presence of unequal power interferers and thermal noise. This result is based on a new expression for the eigenvalues distribution of central Wishart matrices with correlation.
