The probability of error for NFSK with square law combining for diversity correlated Nakagami channels is analyzed. The closed for of expression using characteristic function is derived. The average SNR per branch is considered to be distinct. The effect of different noise powers for various diversity orders and fading channel parameters on probability of error and unequal SNR distribution is b...

The signal-to-noise ratio (SNR) for silicon nanowire field-effect transistors operated in an electrolyte environment is an essential figure-of-merit to characterize and compare the detection limit of such devices when used in an exposed channel configuration as biochemical sensors. We employ low frequency noise measurements to determine the regime for optimal SNR. We find that SNR is not signif...

AIM The influences on the signal-to-noise ratio (SNR) of Displacement ENcoding with Stimulated Echoes (DENSE) MRI of field strength, receiver coil sensitivity and choice of flip angle strategy have been previously investigated individually. In this study, all of these parameters have been investigated in the same setting, and a mutual comparison of their impact on SNR is presented. MATERIALS ...

Abstract In this paper, the expression for SNR has been developed through imaging model. It is concluded that image decreases with increase of number light-emitting points target under same hardware conditions and experimental parameters. Using uniform bright squares different sizes as target, reconstructed calculated. Simulation prototype experiments have proved correctness conclusion. Based o...
