However, this would decrease the spectrum efficiency of ANC systems.
In spectrum sensing, the decreasing of detection performance may decrease the spectrum access opportunity of the SU because of the increasing false alarm probability; however, improving detection performance needs to increase the sensing time, which decreases the data transmission time.
However, none of these papers have considered the transmission in two phases, SU does not transmit over all time slots, it transmits only in the second phase, which decreases the spectrum efficiency as some part of the time slot is used for sensing instead of data transmission.
Adipocyte IR increased and plasma adiponectin decreased across the spectrum of normal glucose metabolism (NGM), impaired glucose metabolism (IGM), and T2DM (both P < 0.001).
However, if the periodical duration is too short, it will cost more time to execute spectrum sensing instead of transmitting SU signals which will decrease the utilization of spectrum holes.
We (4, 22) and others (32, 33) have reported that DI decreases progressively across the spectrum of deteriorating glycemia in youth.
Misdetection leads to interference with the PUs, while false alarms decrease the efficiency of spectrum utilization [6].
Antimicrobial restriction program wound not increase the total amount of prescription and even decrease the usage of broad spectrum antimicrobial agents.
The association of two drugs in the empirical treatment of VAP is recommended in order to increase the spectrum of activity, to decrease the emergence of resistance during treatment, and to improve the bactericidal activity of therapy [ 25].
In order to improve the light reflectance efficiency and to decrease the overlay of tricolor output spectra of a color filter, based on dielectric thin film with nano-scale grating structure, three primary color filters (Red, Green and Blue) located at 635 nm, 530 nm and 455 nm are proposed.
