Sentence examples for existence of spectrum from inspiring English sources

CR has been proposed as the means to promote efficient utilization of the spectrum by exploiting the existence of spectrum holes.

In contrast to this apparent spectrum scarcity has been the pervasive existence of spectrum opportunity as extensive measurements indicate that, at any given time and location, a large portion of licensed spectrum lies unused [2].

The goal of the CR is to enhance spectral efficiency by overlaying a new mobile radio system on an existing one without requiring any changes to the actual licensed system, or we can say that the goal of CR is to promote the efficient use of the spectrum by sensing the existence of spectrum holes.

The existence of discrete spectrum below the essential spectrum is deduced for the Dirichlet Laplacian on tubular neighborhoods (or layers) about hypersurfaces in Rn+1, with various geometric conditions imposed.

If not, it continues spectrum sensing by energy detection alone at TSU. Step III: If RSU also detects the existence of a spectrum hole, TSU starts to transmit data.

But the most important lesson is that we stop regarding men like him as enigmas, totally disconnected from the society they live in, and understand the existence of a spectrum of abuse.

When SU detects the existence of a spectrum hole, it transmits its signal over the licensed channel.

Thus, the capacity achieved at the destination in the case that the source successfully detects the existence of the spectrum hole is C I = max ( C sd, C srd ).

Fluid loss of cement slurry was about 42 ml at 77 °C, indicating a stronger temperature tolerance of ADM and resulting from stronger rigidity of ADM molecule due to the existence of −CH3.TGA spectrum of ADM echoed the results shown in Fig. 4.

The source will begin transmission in the two cases of Ĥ s = H 0 : one is that it successfully detects the existence of the spectrum hole when there is no transmission between the primary users; the other is that it mistakenly detects the appearance of the spectrum hole when the primary users are communicating.

The existence of a spectrum of exchange rates is exemplified by the differing dissociation rate constants of the different plaque proteins (e.g., b = 0.11 s−1 for paxillin, and b = 0.025 s−1 for vinculin).
