Within the framework of linear vector Gaussian channels with arbitrary signaling, closed-form expressions for the Jacobian of the minimum mean square error and Fisher information matrices with respect to arbitrary parameters of the system are calculated ...

Peak to average power reduction using amplitude and sign adjustment [PDF]
In this paper, we propose a method to reduce the peak to mean envelope power ratio (PMEPR) of multicarrier signals by modifying the constellation. For MPSK constellations, we minimize the maximum of the multicarrier signal over the sign and amplitude ...

Sharp bounds by the power mean for the generalized Heronian mean
In this article, we answer the question: For p, ω ∈ ℝ with ω > 0 and p(ω - 2) ≠ 0, what are the greatest value r1 = r1(p, ω) and the least value r2 = r2(p, ω) such that the double inequality Mr1a,b 0 with a ≠ b?

In this paper, we have established some new Hermite–Hadamard–Mercer type of inequalities by using κ–Riemann–Liouville fractional integrals. Moreover, we have derived two new integral identities as auxiliary results.

Optimal sublinear inequalities involving geometric and power means [PDF]
There are many relations involving the geometric means $G_n(x)$ and power means $[A_n(x^{\gamma })]^{1/\gamma }$ for positive $n$-vectors $x$. Some of them assume the form of inequalities involving parameters. There then is the question of sharpness, which is quite difficult in general.

Generalized Fractional Integral Inequalities for $(h,m,s)$-Convex Modified Functions of Second Type [PDF]
New variants of the Hermite - Hadamard inequality within the framework of generalized fractional integrals for $(h,m,s)$-convex modified second type functions have been obtained in this article. To achieve these results, we used the Holder inequality and

Optimal evaluation of a Toader-type mean by power mean
In this paper, we present the best possible parameters p,q∈R$p, q\in\mathbb {R}$ such that the double inequality Mp(a,b)0$a, b>0$ with a≠b$a\neq b$, and we get sharp bounds for the complete elliptic integral E(t)=∫0π/2(1−t2sin2θ)1/2dθ$\mathcal{E}(t)=\int

Geometric inequalities from phase space translations [PDF]
We establish a quantum version of the classical isoperimetric inequality relating the Fisher information and the entropy power of a quantum state. The key tool is a Fisher information inequality for a state which results from a certain convolution ...
