  • Method for improving spectrum sensing and efficiency in cognitive wireless systems
    Patent number: 10645589
    Abstract: Systems and methods for adaptive method exploits self-interference suppression (SIS) and full-duplex (FD) capabilities in cognitive radio and dynamic spectrum access (DSA) systems to enable simultaneous transmission-and-sensing (TS) or transmission-and-reception (TR) over the same frequency channel in a single operation. The adaptive methods enable secondary users or units (SUs) to switch between different modes of operation, taking into account the primary units (PUs) state, the SUs' traffic, and standards' rules. These adaptive methods significantly enhance the SU throughput and reduce the probability of colliding with PU transmissions.
    Type: Grant
