Exact Coverage Analysis of Intelligent Reflecting Surfaces With Nakagami-<i>M</i>Channels

نویسندگان

چکیده

Intelligent Reflecting Surfaces (IRS) are a promising solution to enhance the coverage of future wireless networks by tuning low-cost passive reflecting elements (referred as metasurfaces), thereby constructing favorable propagation environment. Different from prior works, which assume Rayleigh fading channels and do not consider direct link between base station user, this article develops framework based on moment generation functions (MGF) characterize probability user in an IRS-aided systems with generic Nakagami-m presence links. In addition, we demonstrate that proposed is tractable for both finite asymptotically large values metasurfaces. Furthermore, derive channel hardening factor function shape number IRS elements. Finally, closed-form expression calculate maximum range given network parameters. Numerical results obtained Monte-Carlo simulations validate derived analytical results.

Performance Analysis of cooperative SWIPT System: Intelligent Reflecting Surface versus Decode-and-Forward

In this paper, we explore the impacts of utilizing intelligent reflecting surfaces (IRS) in a power-splitting based simultaneous wireless information and power transfer (PS-SWIPT) system and compare its performance with the traditional decode and forward relaying system. To analyze a more practical system, it is also assumed that the receiving nodes are subject to decoding cost, and they are on...

Exact analysis of postdetection combining for DPSK and NFSK systems over arbitrarily correlated Nakagami channels

Postdetection combining is a popular means to improve the bit error performance of DPSK and noncoherent FSK (NFSK) systems over fading channels. Nevertheless, the error performance of such systems in an arbitrarily correlated Nakagami environment is not available in the literature. The difficulty arises from inherent nonlinearity in noncoherent detection and from attempts to determine explicitl...
