MUMBAI, India, Oct. 31 -- Intellectual Property India has published a patent application (202411028751 A) filed by Birla Institute Of Technology And Science, Pilani, Rajasthan, on April 8, 2024, for 'an anchor-based channel estimation system and method for irs-aided 5g and beyond wireless communication systems.'
Inventor(s) include Prateek Mukherjee; and Sandeep Joshi.
The application for the patent was published on Oct. 31, under issue no. 44/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to a single anchor-aided channel estimation system for IRS-based wireless communication networks. In this system, a base station (BS)(102) equipped with multiple transmitting antennas (102A) communicates with users through reflecting array sources via an intelligent reflecting surface (IRS)(104). An anchor device (106), situated between users and the IRS, features a single antenna (106A) capable of transmitting and receiving pilot symbols from both the BS and users. The channel estimation unit (108) is divided into three phases, each strategically designed to estimate specific channel parameters using pilot symbols. Utilizing feedback from the anchor, Channel State Information (CSI) is leveraged to enhance channel parameter estimation at the BS, thereby decreasing the number of unknowns. Furthermore, the anchor enables the exploitation of a common cascaded link strategy, facilitating the estimation of cascaded channels for different users in a passive IRS system. This system promises improved channel estimation performance and reduced pilot symbol overhead in IRS-assisted wireless communication environments."
