Performance Study of Wireless Systems with Switch and Stay Combining Diversity over α-η-μ Fading Channels

Abstract

In this paper, we consider a Switch and Stay Combiner (SSC) diversity scheme operating over α−η−μ fading channel. New and closed-form expressions for the average output SNR (ASNR), the moment-generating function (MGF), the outage probability (P_out), and the average symbol error rate (ASER) for M-ary quadrature amplitude modulation (QAM) signaling are derived. The expressions are obtained in terms of the well-known bivariate Fox’s H-function (BFHF). It is worth pointing out that the BFHF and the bivariate Meijer’s G-function (BMGF) have recently been used extensively in wireless communications literature to study the system's performance. The evaluated results are plotted for channel parameters of interest, and the effect of fading severity on the combiner performance is studied. Moreover, the results are shown to match those previously reported in the literature for other channel models such as η−μ as a special case, which confirms the validity of the obtained expressions. Also, insights on the optimal choice of the switching threshold are provided.

Design and Evaluation of Transmitting Antennas for Solar Power Satellite Systems

“…Due to their planar and rigid construction with low loss, high power handling capability, and high efficiency, SWAAs are more attractive candidates for application in microwave systems such as wireless communications, radars, and SPS systems [16][17][18][19][20][21]. The general principles and components of microwave power transmission systems and their space applications are outlined in [16], while several SWA arrays were designed in [17] with different tapered distributions for high power microwave applications.…”

“…A procedure based on Elliott's model was proposed in [20] to design shaped beam planar arrays. An analytical procedure was introduced in [21], based on Babinet's principle, to design and construct a slotted waveguide antenna array at 2.45GHz.…”
