Executive Summary : | The full duplex (FD) wireless communication theoretically promises double the data rate as compared to the half-duplex communication. However, the performance of the FD system critically relies on self interference (SI) which is caused by the system’s own transmitter/transmitters to its own receiver and it can be dealt by proper designing of analog filter and digital beamforming. The intelligent reflecting surfaces (IRSs) which have been recently introduced by the researchers in wireless communication are made up of meta material also called reflecting elements. These reflecting elements are used to modify the angle and the amplitude of the incident signals impinging on its surface with the help of software defined controller. And thus these elements are used to focus the reflected signals constructively at the desired destination or the receiver. In this proposal, IRS technology is sightseen as the remedy for mitigating the most important hindrance of a FD wireless communication that is SI. The utility and performance of the IRS enhanced system can be checked in terms of system performance, outage probability, etc. Specifically, index modulation (IM) a new modulation tech is also explored in this proposal which will be used to tackle the SI and complexities of a FD system in multi transceiver system. The spectrum efficient index modulation along with IRS may play a big role in future wireless communication. In this proposal, self-interference will be minimized for FD wireless communication system by utilizing transceiver digital beamforming and the properties of IRS. The number of active IRS elements and active IM elements will be estimated and unwanted reflective signals will be cancelled out. Overall the proposal proposes an IRS enhanced FD system which will be used to enhance the energy and spectrum efficiency of the wireless communication system. The proposed work will be demonstrated through testbed implementation and measurement in a practical environment. |
