Novel Results for the Spectral Efficiency and Symbol Error Rate of GSC Receiver over Identical and Uncorrelated Weibull Fading Channels

In this work, we introduce a novel probability density function (PDF)-based expression to obtain the maximum average spectral efficiency (MASE) and the average symbol error rate (ASER) of L-branch Generalized Selection Combining (GSC) receiver over independent and identical Wei bull fading channels. Approximating the output SNR by a simple H-distribution, useful expressions of outage probability, MASE and ASER for some M-ary modulation schemes are derived in terms of Meijer G-function. The approximated PDF is validated by computed simulations using Mathematica software.
