Abstract

In this paper we propose a method to perform tunable spectral sensing using globally coupled oscillators. The suggested system may operate is analog (RF) domain without high speed ADC and heavy digital signal processing. Oscillator arrays may be made of imprecise elements such as nano-resonators. Provided a proper coupling, the system dynamics can be made stable despite the imprecision of components. Global coupling could be implemented using a common load and controlled by digital means to tune the bandwidth. This method may be used for spectral sensing in cognitive radio terminals.
