Introduction: When the Nakagami-m envelope distribution was proposed [1], no information on the phase distribution of the corresponding signal was provided. In fact, to the best of the authors’ knowledge, the Nakagami-m phase-envelope joint probability density function (pdf) has not been established yet, either by physical argument or by empirical evidence [2–4]. Accordingly, the usual uniform ...

This paper presents a simple and efficient simulation model for Nakagami-m fading channels. We first show, via measurement data, that the Nakagami-m distribution provides the best fit for the fading amplitudes of the satellite-to-indoor and satellite-tooutdoor channels. Therefore, finding a viable simulation model for Nakagami-m distribution is very important for the purpose of studying signal ...

ultrasound images suffer of multiplicative noise named speckle. different de-speckling algorithms run either in spatial domain or in transformed domain. in this paper, an adaptive filter in spatial domain according to assume the nakagami distribution as the statistic of log-compressed ultrasound images is used. for de-speckling in transformed domain, the non-sub sampled shearlet transform is us...

In this paper, the Bit Error Rate (BER) performance of OFDM -BPSK system over flat Nakagami fading channels is analyzed. This model is versatile enough to represent fading. Here our approach is based on decomposition of Nakagami random variable into orthogonal random variables with Gaussian distribution envelopes. Finally simulations of OFDM signals are carried with Nakagami faded signal to und...

Efficient simulation models for correlated Nakagami-m fading channels are required for the development, performance evaluation and validation of diversity combining systems in general fading channels. We propose a theoretical explanation of the Nakagami-m distribution, as a natural extension of the Rayleigh fading model. In this model, a Nakagami random variable is viewed as the norm of an mdim...

To assess the performance of maximum-likelihood (ML) based Nakagami m parameter estimators, current methods rely on Monte Carlo simulation. In order to enable the analytical performance evaluation of ML-based m parameter estimators, we study the statistical properties of a parameter Δ, which is defined as the log-ratio of the arithmetic mean to the geometric mean for Nakagami-m fading power. Cl...

The Nakagami statistical parameter has been demonstrated to be capable of detecting the variation of scatterer concentration in a biological tissue. The accuracy and sensitivity of the Nakagami parameter would be varied by the quality of ultrasonic backscattered signals, which is further affected by noise interference. For this reason, the experimental measurements and two-dimensional computer ...

Multipath fading is one of the most common distortions in wireless communications. The simulation of a fading channel typically requires drawing samples from a Rayleigh, Rice or Nakagami distribution. The Nakagami-m distribution is particularly important due to its good agreement with empirical channel measurements, as well as its ability to generalize the well-known Rayleigh and Rice distribut...

In this paper, system performances of selection combining over correlated Nakagami-m channels are analyzed. Selection diversity based on the signal to interference ratio (SIR) is a very efficient technique that reduces fading and cochannel interference influence. Fading between the diversity branches and between interferers is correlated and Nakagami-m distributed with exponential correlation m...
