Low-frequency noise in spin valve sensors
Low frequency noise in giant magnetoresistive spin valves has been studied as a means of optimizing signal to noise ratios and characterizing device performance. The devices studied were sputter deposited NiFe/Cu/NiFe/FeMn ...
Algorithms and architectures for channel estimation in wireless CDMA communication systems
Wireless cellular communication is witnessing a rapid growth in markets, technology, and range of services. An attractive approach for economical, spectrally efficient, and high quality digital cellular and personal ...
Quantifying information coding limits in sensory systems
Neurons code information about sensory stimuli temporally in the times of occurrence of action potentials as well as spatially in the joint discharge patterns of neurons within an ensemble. In this work, we present a ...
Longitudinal recording on FePt and FePtX (X = B, Ni) intermetallic compounds
Near field recording on high coercivity FePt intermetallic compound media using a high Bsat write element was investigated. Untextured FePt media were prepared by magnetron sputtering on ZrO2 disks at a substrate temperature ...
Investigating the electronic properties of carbon nanostructures with scanning tunneling microscopy
Utilizing the scanning tunneling microscope, the electronic and structural properties of a variety of carbon based nanostructures, are explored. Among these, threefold electron scattering on graphite generated by vacancies ...
Experimental demonstration of all-optical CDMA using bipolar codes
Fiber optic networks capable of supporting a large pool of subscribers, many simultaneous users, and high data rates are receiving heightened interest as solutions to a growing communications need. The experiments reported ...
