Keywords:
MIMO systems, self-interference, mutual-interference, full-duplex communicationAbstract
The imagination vision of for our the future of wireless communications is for the a better quality of service, higher data rates, and decreased latency, all of which is an importantform the focus of the fifth generation (5G) technologies. Thus, the prime concept of is a full-duplex single-channel (FDSC) for multiple input, multiple output (MIMO) systems which can provide double throughput and higher spectral efficiency. The design and simulation results of the FDSC communication for MIMO systems are the methods to for transmitting and receive receiving at the same time on the same frequency. The main challenge of full-duplex communication systems are the resulting self-interference and mutual-interference signals. In this paper, we propose a novel technique for the interference cancellation using a pre-defined RF radio frequency circuit network in the analog cancellation part. Our simulation results show that the proposed technique can improve the performance of the transmitting and receiving systems depending on the decrease of the interference powers.
