Exact expressions for single and product moments of generalized order statistics are derived when the underlying population is assumed to have a Rayleigh distribution. Bayesian estimators and highest posterior density (HPD) credible intervals are obtained for the scale parameter and reliability function based on generalized order statistics. We also derive the Bayes predictive estimator and HPD...
In this paper fading models are considered. In particular we divide the models into three classes by separating the received signal in three scale of spatial variation such as fast fading, slow fading (shadowing) and path loss. Moreover, several models for small scale fading are considered such as Rayleigh, Ricean, Nakagami and Weibull distributions. Slow fading is also investigated as well as ...
In this paper, we derive a new selection combining (SC) scheme for noncoherent binary FSK signals on independent (but not necessarily identically distributed) Rayleigh fading channels with -antenna diversity reception. With this combining scheme, we choose the diversity branch having the largest magnitude of the logarithm of the ratio of the a posteriori probabilities (log-APP ratio – LAPPR) of...
In this study, the performance of the proposed receiver with the neural network Multiple Access Interference (MAI) detector is compared with the matched filter bank (classical receiver), neural network that detects user's signal and single user bound for Additive White Gaussian Noise (AWGN) and Rayleigh fading asynchronous channels by computer simulations. There are a lot of study in the litera...
The ergodic capacity, capacity distribution and outage capacity are investigated for MIMO wireless systems under time-varying and frequency-selective Rayleigh fading channels. Our theoretical results and Monte-Carlo simulations show that: (1) if the frequency-selective Rayleigh fading channel impulse response has no inter-tap correlations, then its ergodic capacity is the same as that of the fr...
This paper taught the performance of the proposed sensing models, namely, constant false alarm ratedynamic waveform detector (CFAR-DWD) are categorized as dynamic threshold (DT), two-stage (TS), and adaptive two-stage (ATS) detection for accurately detecting of the static-primary user (PU) signals, where the state of the PU signal not change during the sensing duration. Whereby it is carried ou...
In this paper, we consider a kind of p-Laplacian neutral Rayleigh equation with singularity of attractive type, [Formula: see text] By applications of an extension of Mawhin's continuation theorem, sufficient conditions for the existence of periodic solution are established.
The dimensions in the previous examples are analysed using Rayleigh's Method. Alternatively, the relationship between the variables can be obtained through a method called Buckingham's π. Buckingham ' s Pi theorem states that: If there are n variables in a problem and these variables contain m primary dimensions (for example M, L, T) the equation relating all the variables will have (n-m) dimen...
