The bat algorithm is a swarm intelligence optimization algorithm, which mainly used to solve optimization problems. The proposed algorithm focused on modified constant modulus algorithm, which is also applicable to the constant modulus algorithm. The error function of blind equalization algorithm is used as the evaluation function of the bat algorithm, and then the initial value of the weight vector is calculated adaptively by the bat algorithm. Theoretical analysis is provided to illustrate that the proposed algorithm has a faster convergence speed than the original one and is suitable for almost all blind channel equalization algorithms. The simulation results support the newly proposed improved algorithm. The proposed algorithm could be applied to some more complex wireless channel environments to improve the reception performance of sensor communication systems.<\/jats:p>","DOI":"10.3233\/jifs-189709","type":"journal-article","created":{"date-parts":[[2021,2,26]],"date-time":"2021-02-26T12:02:39Z","timestamp":1614340959000},"page":"4493-4500","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Modified constant modulus algorithm based on bat algorithm"],"prefix":"10.1177","volume":"41","author":[{"given":"Tongtong","family":"Xu","sequence":"first","affiliation":[{"name":"Department of Telecommunication Engineering, Xidian University, Xi\u2019an, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zheng","family":"Xiang","sequence":"additional","affiliation":[{"name":"Department of Telecommunication Engineering, Xidian University, Xi\u2019an, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,2,24]]},"reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.aeue.2015.06.013"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11071-016-3279-y"},{"key":"e_1_3_1_4_2","unstructured":"HaykinS.
