However, they encounter challenges related to meeting the increasing accuracy requirements. This paper introduces the BHM-RK algorithm, a novel approach for constructing REMs in scenarios with multiple transmitters. The algorithm utilizes spatial clustering for transmitter partitioning, Bayesian posterior inference within partitions, and residual Kriging interpolation to address challenges posed by diverse transmitter influences. Experimental validation demonstrates the superior performance of the BHM-RK algorithm in terms of construction accuracy compared to existing methods, highlighting its effectiveness in enhancing precision in REM construction for scenarios with multiple transmitters.<\/jats:p>","DOI":"10.1142\/s2301385025500773","type":"journal-article","created":{"date-parts":[[2024,9,24]],"date-time":"2024-09-24T08:56:24Z","timestamp":1727168184000},"page":"7-19","source":"Crossref","is-referenced-by-count":0,"title":["Radio Environment Map Construction by Residual Kriging Based on Bayesian Hierarchical Model"],"prefix":"10.1142","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2739-9002","authenticated-orcid":false,"given":"Haiyang","family":"Xia","sequence":"first","affiliation":[{"name":"College of Electronic Science and Engineering, National University of Defense Technology, No. 109, Deya Road, Changsha 410073, P.
