Performance Analysis of DE-QPSK and π/4 QPSK with MRC Receiver over η-µ fading channel

Kiranpreet Kaur, T. S. Kamal, J. S. Ubhi


This study presents approximate but simple expression for the average symbol error rate of differentially encoded quadrature phase shift keying (DE-QPSK) and π/4 QPSK with Maximal Ratio Combining (MRC) diversity over independent η-µ fading channels. Numerical results demonstrate the error performance for different values of fading parameter µ for Lth order MRC for Format 1 and Format 2. Furthermore, error performance of both modulation techniques has also been analyzed for Nakagami-m, Rayleigh, one sided Gaussian and Hoyt fading as a special case.
