Phase Offset Aided Index Modulation for UCA-Based OAM Communication

IEEE Access
In this paper, a novel phase offset (PO)-aided index modulation (IM) for orbital angular momentum (OAM) communication, called OAM-PO-IM, is proposed to enhance capacity.

Exponential-type Inequalities Involving Ratios of the Modified Bessel Function of the First Kind and their Applications

, 2013
The modified Bessel function of the first kind, $I_ (x)$, arises in numerous areas of study, such as physics, signal processing, probability, statistics, etc. As such, there has been much interest in recent years in deducing properties of functionals involving $I_ (x)$, in particular, of the ratio ${I_{ +1}(x)}/{I_ (x)}$, when $ ,x\geq 0$. In this

Transient and Steady-State Analysis of an M/PH₂/1 Queue with Catastrophes

Axioms
In the paper, we consider the PH2-distribution, which is a particular case of the PH-distribution. In other words, The first service phase is exponentially distributed, and the service rate is μ. After the first service phase, the customer can to go away

Reflection formulas for order derivatives of Bessel functions

, 2018
From new integral representations of the $n$-th derivative of Bessel functions with respect to the order, we derive some reflection formulas for the first and second order derivative of $J_{\nu }\left( t\right) $ and $% Y_{\nu }\left( t\right) $ for ...

Efficient Calculation of Modified Bessel Functions of the First Kind, $I_ν (z)$, for Real Orders and Complex Arguments: Fortran Implementation with Double and Quadruple Precision

We present an efficient self-contained algorithm for computing the modified Bessel function of the first kind $I_ν(z)$, implemented in a robust Fortran code supporting double and quadruple (quad) precision. The algorithm overcomes the limitations of Algorithm 644, which is restricted to double precision and applies overly conservative underflow and ...
