The initial step in the IRS usually involves estimating the channel between a fixed transmitter and a stationary receiver. After estimating the channel, the problem of finding the most optimal IRS configuration is non-convex, and involves a huge search in the solution space. In this work, we propose a novel and customized technique which efficiently estimates the channel and configures the IRS with fixed transmit power, restricting the IRS coefficients to\u00a0{1,\u22121}. The results from our approach are numerically compared with existing optimization techniques.The key features of the linear system model under consideration include a Reconfigurable Intelligent Surface (RIS) setup consisting of 4096 RIS elements arranged in a 64 \u00d7 64 element array; the distance from RIS to the access point measures 107 m. NLOS users are located around 40 m away from the RIS element and 100 m from the access point. The estimated variance of noise\u00a0NC\u00a0is 3.1614\u00a0\u00d7\u00a010\u221220. The proposed algorithm provides an overall data rate of 126.89 (MBits\/s) for Line of Sight and 66.093 (MBits\/s) for Non Line of Sight (NLOS) wireless communication.<\/jats:p>","DOI":"10.3390\/fi16080272","type":"journal-article","created":{"date-parts":[[2024,7,30]],"date-time":"2024-07-30T15:25:23Z","timestamp":1722353123000},"page":"272","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["A Low-Complexity Solution for Optimizing Binary Intelligent Reflecting Surfaces towards Wireless Communication"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0784-1446","authenticated-orcid":false,"given":"Santosh A.","family":"Janawade\u00a0","sequence":"first","affiliation":[{"name":"Department of Electronics and Communication Engineering, National Institute of Technology Karnataka, Mangalore 575025, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9730-7997","authenticated-orcid":false,"given":"Prabu","family":"Krishnan\u00a0","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, National Institute of Technology Karnataka, Mangalore 575025, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Krishnamoorthy","family":"Kandasamy\u00a0","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, National Institute of Technology Karnataka, Mangalore 575025, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shashank S.","family":"Holla\u00a0","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, National Institute of Technology Karnataka, Mangalore 575025, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karthik","family":"Rao\u00a0","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, National Institute of Technology Karnataka, Mangalore 575025, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aditya","family":"Chandrasekar\u00a0","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronics Engineering, National Institute of Technology Karnataka, Mangalore 575025, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Kadir, E.A., Shubair, R., Rahim, S.K.A., Himdi, M., Kamarudin, M.R., and Rosa, S.L.
