TCS multi-antenna LTE sensing agent

[<< Back to Training Days overview]

The feasibility of parallel sensing performed by an opportunistic device on a LTE incumbent system has been proven in CREW Usage Scenario (US) 5 - Cognitive systems and cellular networks. Thanks to the use of an antenna array (up to 4 Rx antennas) and smart antenna processing, no quiet time slot needs to be inserted in the waveform of the opportunistic system in order to perform sensing. Indeed, thanks to the spatial rejection capability of the TCS multi-antenna system, the opportunistic device can detect the presence of a LTE incumbent system even if it also receives the (opportunistic) signal dedicated to it, even with a very low signal to interference ratio.
