Analysis of Achievable Rate for SISO, MISO and MIMO-Orthogonal Frequency-Division Multiplexed (OFDM) Systems with Reconfigurable Intelligent Surface

The world has started using fifth generation mobile network, with over 1billion people now feeling the speed and power of 5G technology, testing and experiments for beyond 5G networks have started already. One of the most popular technical hardware that shows a potential to enhance this technology is Intelligent reflecting surfaces (IRSs). These have been in the picture for considerable amount of time, these are a low-cost passive element made up on PIN diodes. Intelligent reflecting surfaces (IRSs) also known as reconfigurable intelligent surfaces (RISs) have the capacity to direct the electromagnetic (EM) waves to a particular path. The 3D- Passive meta surface is digitally controlled and has low energy consumption and operates in full-duplex mode. The various Orthogonal Frequency-Division Multiplexed (OFDM) Systems when configured with IRS shows different trends, in the research article the behavior of Achievable rate for Single-Input Single Output (SISO), Multiple-Input Single-Output (MISO) and Multiple-Input Multiple-Output (MIMO) systems have been analyzed. The analyses have been done taking into consideration the mid-band 5G spectrum.
