| Abstract | In-Band Full-Duplex transmissions are promising solutions for wireless 5G small cell communication scenarios. It allows to increase the overall capacity under certain conditions. In this paper we evaluate two combined techniques to mitigate the analog self-interference. Instead of using high performance components with high linearity and high bandwidth for a frequency band, a single SDR chip has been chosen. Based on its characteristics and its simple architecture, a compact and low complexity test bench is proposed to reduce the undesired self-interference. The analog self-interference cancellation reaches 71 dB over 40 MHz bandwidth with a transmitted power of 12 dBm. © 2017 AEIT. |
