The average signal-to-noise ratio (SNR) of a generalized selection combining scheme, in which the m diversity branches (m L, where L is the total number of diversity branches available) with the largest instantaneous SNR’s are selected and coherently combined, is derived. A Rayleigh fading channel is assumed, and a simple closed-form expression for the SNR(More)
Several methods of diversity combining for a Rayleigh-faded channel are evaluated and compared. The methods considered are, for coherent reception, maximal ratio combining (MRC), selection combining (SC), and a generalization of SC, whereby the two (three) signals with the two (three) largest amplitudes are coherently combined. We will call this method(More)
Reference [1] introduced optimum selection combining (OSC) for binary phase shift keyed signals which selects the diversity branch having the maximum a posteriori probability. It performs much closer to maximal ratio combining (MRC) than the conventional selection combining (CSC) which selects the diversity branch having the maximal instantaneous signal(More)
RFID technology holds the promise of real-time identifying, locating and monitoring physical objects. To achieve these goals, RFID events need to be collected efficiently and composed expressively. Furthermore, these events have unique characteristics, such as locomotive, temporal and history oriented which should be considered and integrated into an event(More)
Retinal ganglion cells (RGCs) are preferentially lost in glaucoma or optic neuritis. In the present study, we investigated the protective effect of mircoRNA 100 (miR-100) against oxidative stress induced apoptosis in RGC-5 cells. Rat RGC-5 cells were cultured in plates and H2O2 was added to induce oxidative stress. TUNEL assay and qRT-PCR showed H2O2(More)
The Internet of Things (IOT) is the new network of integration of radio frequency identification (RFID) with the Internet, and it has the similar requirement of the resource addressing as the Internet. The properties of the IOT make the differences between the resource addressing in the IOT (RA-IOT) and that in the Internet. There are some peculiar problems(More)
