Near optimality of the sinc approximation is established in a variety of spaces of functions analytic in a strip region about the real axis, each space being characterized by the decay rate of their elements (functions) in the neighborhood of the infinity.

Wireless communications became an integrated part of the human life. Fifth generation (5G) is modern communication which provides enhanced mobile broadband (eMBB), ultra reliable low latency (URLLC), and massive machine type (mMTC). Thus, 5G have to provide coverage multi-numerology devices, therefore, modulation access schemes are suggested in literature such as cyclic prefix orthogonal freque...

In this article, we give a formula for the generalization of binomial coefficient to complex numbers as linear combination sinc functions. We then general compute integral on real line product and given function, which, in some cases, turns out be equal series their values integers. Finally, establish list identities obtained by applying these formulas.
