Quadrature spatial modulation (QSM) in cognitive radio (CR) is a new spectral efficient multiple-input multiple-output (MIMO) digital modulation technique. In QSM, the spatial constellation diagram of conventional spatial modulation (SM) system is extended to include both in-phase and quadrature components of the data symbol. As such, QSM combined with CR(More)
This paper derives novel, unified, and exact closed-form analytical expressions for the moment generating function (MGF), the generalized moments, and the average symbol error probability (SEP) of wireless communication systems that operate over the α - η - β fading channels. The derived expressions are then used to analyze the(More)
In this paper, we present a unified approach to analyze the average bit error probability (BEP) in generalized fading channels subject to additive generalized Gaussian noise (AGGN). Specifically, we assume that the fading channel is such that the received signal envelope, X, is a random variable that has the probability density function (pdf) given by the(More)
