Asymptotic BEP and SEP of Differential EGC in Correlated Ricean Fading and Non-Gaussian Noise
— In this paper, we study the asymptotic behavior of the bit–error probability (BEP) and symbol–error probability (SEP) of differential M–ary phase–shift keying with differential equal gain combining (DEGC) in correlated Ricean fading and non–Gaussian noise, which in our definition also includes interference. We derive simple and easy–to–evaluate asymptotic BEP and SEP expressions which show that at high signal– to–noise ratios (SNRs) the performance of DEGC depends on certain moments of the noise and interference impairing the transmission. We provide closed–form expressions for these moments for practically important types of noise such as Gaussian noise, Gaussian mixture noise, and correlated co–channel interference. In addition, we show that the performance loss of DEGC compared to coherent maximum ratio combining (MRC) is always 3 dB independent of the type of noise if only one diversity branch is available but strongly depends on the type of noise if mult...
