Performances analysis of a coupled differential oscillators network using the contour graph approach

Abstract

The beamforming allowing the angle control for transmitted and received signals, is one of the most important challenge for the next generation of radio communication systems. Indeed a key point for the development of radio communication systems is to propose an electronic system associated with an antenna array architecture able to orientate the communications in the best direction. For this, magnitude and phase ponderations have to be applied on each antenna to assume the beamforming. Among the different solutions we find multi antenna arrays, which can be controlled by using oscillator arrays. In this context, this paper presents performances analysis in terms of sensitivity of the phase shift for different components of differential oscillators using the contour graph approach.
