Implementation of Digital Self-Interference Cancellation in LTE-based CCFD Transmission

Abstract

In this paper, we propose a real-time and scalable digital cancellation algorithm to cancel the self-interference signal. We implement this algorithm in the FPGA of NI USRP-2953R platform by using LabVIEW to program it through the PCIe. At the end of this paper, we demonstrate the real-time video stream between two platforms at the central frequency 2.2GHz to 2.5GHz with 20MHz bandwidth in the LTE framework.
