Performance analysis for differential phase shift keying signals with Equal Gain Combining over Nakagami fading channels

Abstract

The error probability of DPSK signals in Nakagami fading with EGC diversity reception is analyzed. The error rate is expressed as a (L + 1)-fold integral that contains only simple mathematical functions for L channel reception. The multiple integrals are easily evaluated with the Gauss-Legendre quadrature. Numerical values for the error rates of binary, quaternary and octonary DPSK signals are presented for several fading severity levels.
