Closed-Form Hyper-Rayleigh Mode Analysis of the Fluctuating Double-Rayleigh with Line-of-Sight Fading Channel

The research studies hyper-Rayleigh behavior of a wireless communication system functioning in the presence generalized multipath fading. Although initial metric (hyper-Rayleigh mode (HRM)) is quite informative, it defined only asymptotically (i.e., for infinitely increasing SNR). In spite mathematical simplifications brought by such definition this case most performance characteristics defining HRM can be easily evaluated), sufficiently limits its applications since, evidently, real-life systems function finite (and usually not very high) SNR. study presents novel approach to fading channel analysis signal-to-noise ratio (fHRM)). proposed (fHRM) studied on newly presented model-fluctuating double-Rayleigh with Line-of-Sight (fdRLoS) model. To accomplish this, expressions two channel-dependent Amount Fading (AoF) and Outage Probability (OP)) were derived exact form valid arbitrary parameters. Based expressions, SNR map obtained, which helps identify parameters’ values corresponding specific propagation scenarios, further deployed analyze problem link physical layer security quantified terms probability strictly positive secrecy capacity (SPSC). Numerical verification closed-form was performed. Several peculiarities are observed discussed.
