Background noise, multipath extension, and Doppler frequency shift are all factors that affect high\u2010speed and stability for underwater communication. Orthogonal frequency division multiplexing (OFDM) is a modulation technology with high spectrum efficiency and strong anti\u2010multipath ability, usually used in high\u2010speed underwater acoustic communication. Signal arrival time detection and timing estimation before receiving data is an essential module in an underwater communication system. Timing estimation error will seriously affect the demodulation of the signal. In order to solve the problem of a complex channel environment in underwater acoustic communication system, a timing estimation method is proposed based on multiple hyperbolic frequency\u2010modulated (MHFM) signals. In order to improve the performance of underwater acoustic communication systems, this article proposes an iterative method of correlation\u2010sum\u2010mean absolute error (MAE) based on hyperbolic frequency\u2010modulated (HFM). The simulation results show that the proposed method can provide better performance and higher timing estimation accuracy under the conditions of low signal\u2010to\u2010noise ratio (SNR) and Doppler effect under oceanic noise channel and Doppler spread channel.<\/jats:p>","DOI":"10.1002\/ett.4636","type":"journal-article","created":{"date-parts":[[2022,8,22]],"date-time":"2022-08-22T23:55:15Z","timestamp":1661212515000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Timing estimation of multiple hyperbolic frequency\u2010modulated signals based on multicarrier underwater acoustic communication"],"prefix":"10.1002","volume":"33","author":[{"given":"Xuerong","family":"Cui","sequence":"first","affiliation":[{"name":"College of Oceanography and Space Informatics China University of Petroleum (East China)  Qingdao China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7091-8592","authenticated-orcid":false,"given":"Peihao","family":"Yan","sequence":"additional","affiliation":[{"name":"College of Oceanography and Space Informatics China University of Petroleum (East China)  Qingdao China"}]},{"given":"Juan","family":"Li","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology China University of Petroleum (East China)  Qingdao China"}]},{"given":"Hao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering Ocean University of China  Qingdao China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3924-9001","authenticated-orcid":false,"given":"Shibao","family":"Li","sequence":"additional","affiliation":[{"name":"College of Oceanography and Space Informatics China University of Petroleum (East China)  Qingdao China"}]},{"given":"Jianhang","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology China University of Petroleum (East China)  Qingdao China"}]}],"member":"311","published-online":{"date-parts":[[2022,8,22]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/JSEN.2015.2434890"},{"key":"e_1_2_9_3_1","doi-asserted-by":"crossref","unstructured":"ZhangD FanM ZhaW et al.Research on synchronization technology for OFDM underwater acoustic communication system.
