This paper presents a new method of designing a beamformer having a desired nearfield broadband beampattern. The methodology uses the spherical harmonic solution to the wave equation to transform the desired nearfield beampattern to an equivalent farfield beampattern. A farfield beamformer is then designed for a transformed farfield beampattern that, if achieved, gives the desired nearfield pat...

In this study, a simple and compact antenna structure with dual-port dual-mode operating in single-band is proposed for wireless body area network. This composed of rectangular ring patch antenna, which shorted the outer edge to generate an omni-azimuthal radiation pattern. pattern desired on-body communication level. A substrate integrated waveguide cavity-backed slot also located at centre pr...

We describe a new theoretical framework for robot-aided training of arm movements. This framework is based on recent studies of motor adaptation in human subjects and on general considerations about adaptive control of artificial and biological systems. We propose to take advantage of the adaptive processes through which subjects, when exposed to a perturbing field, develop an internal model of...

This paper presents a new pattern synthesis algorithm for arbitrary arrays based on adaptive array theory. With this algorithm, the designer can efficiently control both mainlobe shaping and sidelobe levels. The element weights optimize a weighted L2 norm between desired and achieved patterns. The values of the weighting function in the L2 norm, interpreted as imaginary jammers as in Olen and C...

This paper presents a simulation study of a smart antenna (SA) system based on direction-of-arrival (DOA) estimation is based on the MUltiple SIgnal Classification (MUSIC) algorithm for finding the Position Location (PL) of the desired user. The beamformer steer the main beam towards the desired user and nullify all other interferer, through adaptive beamforming using Least Mean Square (LMS) al...
