The receiver integrates soft successive interference cancellation, successive weight update sparse Bayesian learning channel estimation based on approximate message passing (SWUSBL-AMP), and an improved channel update decision. After the first iteration, the improved channel update decision first estimates the channel of each subblock using the interference-cancelled signals from the previous iteration, avoiding the mismatch of time-varying channels. By running the factor graph serially, the SWUSBL-AMP channel estimation algorithm enables the factor graph of the current subblock to utilize the messages updated by the previous subblock, and update the correlation weighting factors, to accelerate the convergence speed and further improve the channel estimation accuracy. Using the experimental data collected in the South China Sea in 2023 for processing, the results demonstrate that the bit error rate performance of the proposed receiver is better than that of other receivers of the same type. Moreover, we also verify the complexity of the proposed SWUSBL-AMP algorithm can be nearly an order of magnitude lower than that of other algorithms.<\/jats:p>","DOI":"10.1121\/10.0036141","type":"journal-article","created":{"date-parts":[[2025,3,17]],"date-time":"2025-03-17T12:04:24Z","timestamp":1742213064000},"page":"1807-1820","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":6,"title":["Successive weight update sparse Bayesian learning based receiver for multiuser underwater acoustic communications"],"prefix":"10.1121","volume":"157","author":[{"given":"Xueli","family":"Sheng","sequence":"first","affiliation":[{"name":"National Key Laboratory of Underwater Acoustic Technology, Harbin Engineering University 1 , Harbin 150001,","place":["China"]},{"name":"Key Laboratory for Polar Acoustics and Application of Ministry of Education, Harbin Engineering University, Ministry of Education 2 , Harbin 150001,","place":["China"]},{"name":"College of Underwater Acoustic Engineering, Harbin Engineering University 3 , Harbin 150001,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zheng","family":"Wu","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Underwater Acoustic Technology, Harbin Engineering University 1 , Harbin 150001,","place":["China"]},{"name":"Key Laboratory for Polar Acoustics and Application of Ministry of Education, Harbin Engineering University, Ministry of Education 2 , Harbin 150001,","place":["China"]},{"name":"College of Underwater Acoustic Engineering, Harbin Engineering University 3 , Harbin 150001,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"Wei","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Underwater Acoustic Technology, Harbin Engineering University 1 , Harbin 150001,","place":["China"]},{"name":"Key Laboratory for Polar Acoustics and Application of Ministry of Education, Harbin Engineering University, Ministry of Education 2 , Harbin 150001,","place":["China"]},{"name":"College of Underwater Acoustic Engineering, Harbin Engineering University 3 , Harbin 150001,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guangjun","family":"Zhu","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Underwater Acoustic Technology, Harbin Engineering University 1 , Harbin 150001,","place":["China"]},{"name":"Key Laboratory for Polar Acoustics and Application of Ministry of Education, Harbin Engineering University, Ministry of Education 2 , Harbin 150001,","place":["China"]},{"name":"College of Underwater Acoustic Engineering, Harbin Engineering University 3 , Harbin 150001,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiao","family":"Han","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Underwater Acoustic Technology, Harbin Engineering University 1 , Harbin 150001,","place":["China"]},{"name":"Key Laboratory for Polar Acoustics and Application of Ministry of Education, Harbin Engineering University, Ministry of Education 2 , Harbin 150001,","place":["China"]},{"name":"College of Underwater Acoustic Engineering, Harbin Engineering University 3 , Harbin 150001,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanan","family":"Tian","sequence":"additional","affiliation":[{"name":"Key Laboratory of Science and Technology on Advanced Underwater Acoustic Signal Processing, Chinese Academy of Sciences 4 , Beijing 100190,","place":["China"]},{"name":"Institute of Acoustics, Chinese Academy of Sciences 5 , Beijing 100190,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2025,3,17]]},"reference":[{"key":"2025031712041852400_c1","doi-asserted-by":"publisher","first-page":"525","DOI":"10.1109\/JOE.2011.2166660","article-title":"Time reversal receivers for high data rate acoustic multiple-input\u2013multiple-output communication","volume":"36","year":"2011","journal-title":"IEEE J.
