AI Article Synopsis
- This paper introduces a new method for spectral sensing that uses coupled oscillators with global inhibition, which allows for flexibility in tuning without the need for fast analog-to-digital converters or complex digital processing.
- The proposed oscillator arrays can utilize imprecise components, like nanoresonators, and still maintain stable system dynamics through effective coupling.
- The global coupling mechanism can be adjusted digitally to modify the bandwidth, making this method suitable for applications in cognitive radio technology.
Article Abstract
In this paper we propose a method to perform tunable spectral sensing using globally inhibitory coupled oscillators. The suggested system may operate in the analog radio frequency (RF) domain without high speed ADC and heavy digital signal processing. Oscillator arrays may be made of imprecise elements such as nanoresonators. Provided there is a proper coupling, the system dynamics can be made stable despite the imprecision of the 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.
