The effect of skin tissue on the scattering of the MRI RF field by deep brain stimulation (DBS) leads is analyzed. RF induced heating occurs in the tissue surrounding the electrodes at the end of such a medical lead. The electric field and the induced temperature rise are found by solving the wave and heat equations. Spatial plots of the solutions are(More)
In this paper we present the impact of femtocell underlay deployment sharing same radio frequency resources with urban macro-cell in terms of throughput performance of enodeBs in the presence of inter cell interference that a femto base station environment adds to users served by enodeBs and vice versa. The performance of the two systems, one with femto(More)
This paper derives the utility of recursion based adaptive algorithm for the cancellation of interference in open space in a noisy environment. Several parameters of interest like polarization, transmitter power, noise profile, filter characteristics and sampling rate are contemplated. We test the proficiency and ability of recursive least square (RLS)(More)
During magnetic resonance imaging (MRI), an implanted lead present in a patient's body scatters the radiofrquency (RF) field used for magnetic resonance. The resultant RF field can achieve very high values in the vicinity of the implant structure. The conduction currents flowing in tissue can cause dangerous resistive heating. Therefore scattering by(More)
—We present new outer bounds to the individual rates and the conditions under which these bounds become tight for the symmetric Gaussian cog-nitive radio (CR) channel in the low interference gain regime. The CR transmitter is assumed to use dirty paper coding while deriving the outer bounds. The capacity of the CR channel in the low interference scenario is(More)
