Measurement of Internal Self-Interference of Usrp Family of Devices in Full-Duplex Operations
It is always been desirable to operate radios in full-duplex (FDX) mode to harness the maximum spectral efficiency despite the challenges it puts forth. Before validating any FDX schemes using a radio, we should know the characteristics of the radio in FDX operation. In this paper, the results from the measurement are presented for a set of widely used software-defined radio (SDR) platform, universal serial radio peripheral (USRP) such as N210, B210, and E310. The measurements includes the measurement of internal leakage suffered by these radios, operational range of transmitter gain to operate in FDX mode and their limitations. The internal leakage suffered by the USRPs is not uniform and varies across the family of devices.
