We also extend the proposed scheme to the doubly-selective channels, in which the unitary space-time modulation can work as the unitary space-frequency modulation by utilizing orthogonal frequency division multiplexing (OFDM) [16].
The general case is firstly discussed, followed by the special case in which the unitary signals within the constellation set are mutually orthogonal.
To find a more optimal user set and prevent the waste of the feedback resource at the base station, we present a multiuser multiple-input multiple-output system using a random beamforming (RBF) scheme, in which one unitary matrix is used.
It is a political system in which an otherwise unitary state develops a federal relationship with a territorially, ethnically, or culturally distinct community while all the other parts of the state remain under unitary rule.
The original theoretical setting for quantum computation is the gate model [1] in which a global unitary that acts on a register of qubits, which computes the solution to some problem, is decomposed into a sequence of fundamental gates that are applied to the register.
Taxation of investment income received from a nondomiciliary taxpayer's investment in another corporation requires only that the investment income be sufficiently related to the taxpayer's in-state business, not that the taxpayer's business and the corporation in which it invests be unitary.
It's also possible that there is a sense in which grounding is both unitary and variegated.
And this is exactly the situation feared by officials like Secretary of State John Kerry, in which Israel is a unitary "apartheid state with second-class citizens".
For this study, we defined validity following modern conceptualizations in which validity is a unitary concept with construct validity as a core, deriving validity evidence from several sources such as assessments of content validity, the response process, the internal structure of the instrument, its relationships to other variables and its consequences [ 22, 24].
