Abstract

In this paper, we show an experimental demonstration of the suppression of self-interference (SI) using the antenna domain SI-Cancellation (SIC) method in a co-linearly polarised shared-radiator-based full-duplex antenna system. Here, we initially show the signal impairment in the received QPSK constellation due to the presence of SI signal using a conventional microstrip full-duplex antenna system without SIC. Further, the improvement in the received QPSK signal quality is exhibited using a shared-radiator full-duplex (SR-FD) antenna with reduced SI using antenna domain cancellation. A low-cost in-house experimental set-up is prepared using Adalm-Pluto software-defined radio (SDR) and MATLAB Simulink for the experiment. The proposed FD antenna system operates at a 5.9 GHz operating frequency, suitable for V2X-ITS application. © 2023 IEEE.
