Ergodic Mutual Information for Generalized Fadings

Novel expressions for the ergodic mutual information (EMI) under BPSK modulation of single-input single-output (SISO) systems operating in generalized fading channels, namely Rayleigh, Nakagami-$m$, Rician, $\eta$-$\mu$ and $\kappa$-$\mu$, are derived. Different from the conventional results of the EUI, our developed expressions contain only the simplest numerical calculations, but no any Meijer's G-functions, which must be implemented in the specific computing software.
