Symbol Error Probability Analysis of Quadrature Phase Shift Keying Using Hybrid Diversity Technique over Rayleigh Fading
نویسنده
چکیده
The exact expressions for the symbol error probability (SEP) of hybrid selection maximal ratio combining wireless systems for quadrature phase shift keying (QPSK) is derived and analyzed in multipath fading environment. Independent rayleigh fading diversity branch is assumed for analysis with equal Signal-to-Noise ratio averaged over the fading channels and coherent detection of quadrature phase shift keying(QPSK) is considered. Virtual branch technique, which transforms the ordered physical branches, which are dependent into independent, and identically distributed virtual branches is used, there by permitting the derivation of exact symbol error probability (SEP) expressions.

Virtual branch analysis of symbol error probability for hybrid selection/maximal-ratio combining in Rayleigh fading
In this paper, we derive analytical expressions for the symbol error probability (SEP) for a hybrid selection/maximalratio combining (H-S/MRC) diversity system in multipath-fading wireless environments. With H-S/MRC, out of diversity branches are selected and combined using maximal-ratio combining (MRC). We consider coherent detection of -ary phase-shift keying (MPSK) and quadrature amplitude m...
