Since the performance metrics of digital communication systems over composite multipath/ lognormal fading channels is intractable, a mixture gamma (MG) fading model is used to approximate Nakagami-lognormal (NL) fading model. By using MG fading model, the ergodic capacity of dualhop semi-blind amplify-and-forward relaying systems is investigated over independent non-identical composite NL fadin...

Bluetooth is a promising wireless technology designed for personal ad hoc networks. This paper proposes a piconet scheduling algorithm based on the estimated channel state information. This policy is appropriate for wireless and mobile communications networks. The proposed algorithm is suitable for Bluetooth networks employing power class one devices, which can cover ranges up to 100 meters, al...

Consider n source-destination pairs randomly located in a shared wireless medium, resulting in interference between different transmissions. All wireless links are modeled by independently and identically distributed (i.i.d.) random variables, indicating that the dominant channel effect is the random fading phenomenon. We characterize the throughput of one-hop communication in such network. Fir...

In this paper we present theoretical data in support of the unified indoor geolocation channel model namely (1) path loss and (2) multipath distribution models. First, the path loss model is currently accepted to be a function of the transmitter and receiver geometry and frequency of operation. Second, the most widely used and accepted indoor channel multipath distribution models are Nakagami w...

In communications theory, Nakagami distribution (NKD) is used to model scattered signals that reach a receiver from different paths. In order to use NKD to model a given set of data, we will have to estimate its parameters from the given data. Method of L-Moments (MLM) is being compared with Method of Moments (MOM) for estimating the parameters of NKD. In this study, we have derived its first t...

In this letter, capitalizing on the proof of a theorem presented by Blumenson and Miller many years ago, a useful closed formula for the exponentially correlated -variate Nakagamiprobability density function is proposed. Moreover, an infinite series approach for the corresponding cumulative distribution function is presented. Bounds on the error resulting from the truncation of the infinite ser...
