Cognitive Reconfigurable RF Technology

摘要

The present invention provides a radio architecture that contains a main radio path and a sensing path. The parameters of the main radio path are controlled by a cognitive engine. The main radio path is tuned to a desired frequency band. The sensing path is used to monitor the spectrum around the desired frequency band. To minimize effects of undesired non-linearity on sensing, sensing path may have a lower gain setting. The cognitive engine determines the optimal setting of the main RF front-end with respect to the current state of the spectrum.

1. A signal detection method comprising the steps of:
providing a RF front-end configured to have at least one flexible main radio path, said at least one flexible main radio path having a plurality of configurable parameters, and at least one sensing radio path; said flexible main radio path is tuned to a desired frequency band; said sensing path monitors a spectrum around said desired frequency band to create spectrum sensing data; and providing said spectrum sensing data to a cognitive engine configured to determine the optimal values of said configuration parameters in terms of minimizing the distortion of a desired signal at the output of said flexible main radio path.
