The generalized K-fading model, characterized by two parameters, k and m, was recently shown to accurately capture the effects of composite shadowing and multipath fading in wireless communication systems. In this paper, the authors derive closed-form expressions for the bit error probability of two non-coherent transmission schemes over L diversity branches being subject to generalized K-fading. Specifically, focus is on binary Differential Phase-Shift Keying (DPSK) and binary non-coherent Frequency-Shift Keying (FSK) modulation with equal-gain combining at the receiver. They also derive expressions for the asymptotic diversity order, which reveal an interesting interplay between the two fading parameters k and m.
