Abstract :
The main challenge of operating a radio in full duplex mode, is the direct feedback from its transmission to its reception which is the self interference. However, the internal leakage within the radio has the potential to distort the received signal. This paper presents the measured leakage observed in N210 one of the Universal Serial Radio Peripheral (USRP) family of devices. Also, suppression mechanism has been evaluated in both in hardware and software.
