A MATLAB program for the computation of the confluent hypergeometric function Φ2
(2016-09-22)We here present a sample MATLAB program for the numerical evaluation of the confluent hypergeometric function Φ2. This program is based on the calculation of the inverse Laplace transform using the algorithm suggested by ... -
A New Framework for the Performance Analysis of Wireless Communications under Hoyt (Nakagami-q) Fading
(IEEE, 2017)We present a novel relationship between the distribution of circular and non-circular complex Gaussian random variables. Specifically, we show that the distribution of the squared norm of a non-circular complex Gaussian ... -
Asymptotically Exact Approximations for the Symmetric Difference of Generalized Marcum-Q Functions
(IEEE, 2015)In this paper, we derive two simple and asymptotically exact approximations for the function defined as ΔQm(a, b) =Δ Qm(a, b) - Qm(b, a). The generalized Marcum Q-function Qm(a, b) appears in many scenarios in communications ... -
A data-driven scheduler model for QoE assessment in a LTE radio network planning tool
(2019-11-19)The use of static system-level simulators is common practice for estimating the impact of re-planning actions in cellular networks. In this paper, a modification of a classical static Long Term Evolution (LTE) simulator ... -
An energy-efficient integration of a digital modulator and a Class-D amplifier
(MDPI, 2020-08-16)Energy consumption is always a key feature in devices powered by electric accumulators. The power amplifier is the most energy-demanding module in mobile devices, portable appliances, static transceivers, and even nodes ... -
On the Calculation of the Incomplete MGF with Applications to Wireless Communications
(IEEE, 2017)The incomplete moment generating function (IMGF) has paramount relevance in communication theory, since it appears in a plethora of scenarios when analyzing the performance of communication systems. We here present a general ... -
Optimal Fair Scheduling in S-TDMA Sensor Networks for Monitoring River Plumes
(Hindawi Publishing Corporation, 2016)Underwater wireless sensor networks (UWSNs) are a promising technology to provide oceanographers with environmental data in real time. Suitable network topologies to monitor estuaries are formed by strings coming together ... -
Optimal scheduling and fair servicepolicy for STDMA in underwater networks with acoustic communications
(MDPI, 2018-02)In this work, a multi-hop string network with a single sink node is analyzed. A periodic optimal scheduling for TDMA operation that considers the characteristic long propagation delay of the underwater acoustic channel is ... -
Self-Organizing and Scalable Routing Protocol (SOSRP) for Underwater Acoustic Sensor Networks
(MDPI, 2019-07-16)Underwater Acoustic Sensor Networks (UASN) have two important limitations: a very aggressive (marine) environment, and the use of acoustic signals. This means that the techniques for terrestrial wireless sensor networks ... -
The Fluctuating Two-Ray Fading Model: Statistical Characterization and Performance Analysis
(IEEE, 2017)We introduce the fluctuating two-ray (FTR) fading model, a new statistical channel model that consists of two fluctuating specular components with random phases plus a diffuse component. The FTR model arises as the natural ... -
The κ-µ Shadowed Fading Model with Integer Fading Parameters
(IEEE, 2017)We show that the popular and general κ-μ shadowed fading model with integer fading parameters μ and m can be represented as a mixture of squared Nakagami- m̂ (or Gamma) distributions. Thus, its PDF and CDF can be expressed ... -
Tilted subwavelength gratings: controlling anisotropy in metamaterial nanophotonic waveguides
(2018-10-24)Subwavelength grating (SWG) structures are an essential tool in silicon photonics, enabling the synthesis of metamaterials with a controllable refractive index. Here we propose, for the first time to the best of our ...
