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 investigates how to increase the efficiency of a photovoltaic/energy storage generation unit supplying dynamic loads by regulating and managing both the photovoltaic generator and the storage battery charge-discharge modes. The proposed photovoltaic/energy storage unit is proposed to supply an induction motor driven industrial pump with(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)
Modern cooperative telecommunication networks are currently utilizing a relay terminal, which is frequently exploited as an intermediate stage. This technique is vitally significant for the sake of performance enhancement and coverage extension with no further increment of the transmitted RF power. These benifits can be further improved by introducing(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)
