In this paper, we have done research on the signal detection problem in the AmBC system and proposed to use the k-means clustering analysis algorithm to detect the received backscattered signal. At the same time, in order to obtain a more obvious clustering center, this paper introduces a multi-antenna receiver channel detection mechanism. The proposed method can compare and analyze the energy received by the receiver antennas in an extremely short time slots. The channel state information between the reader and the backscatter tag is obtained, and the optimal communication channel is selected, thereby effectively improving the clustering effect. Finally, a large number of experimental simulations are provided to compare and analyze the corresponding BER performance to confirm our theoretical research.<\/jats:p>","DOI":"10.1093\/comjnl\/bxz143","type":"journal-article","created":{"date-parts":[[2019,10,28]],"date-time":"2019-10-28T12:07:48Z","timestamp":1572264468000},"page":"844-856","source":"Crossref","is-referenced-by-count":1,"title":["Multiantenna Receiver Signal Detection in AmBC Based on Cluster Analysis"],"prefix":"10.1093","volume":"63","author":[{"given":"Jumin","family":"Zhao","sequence":"first","affiliation":[{"name":"College of Information and Computer, Taiyuan University of Technology, 209, Daxue Street, Jinzhong, Shanxi, China, 030600"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liang","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Information and Computer, Taiyuan University of Technology, 209, Daxue Street, Jinzhong, Shanxi, China, 030600"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deng'ao","family":"Li","sequence":"first","affiliation":[{"name":"College of Information and Computer, Taiyuan University of Technology, 209, Daxue Street, Jinzhong, Shanxi, China, 030600"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2020,1,2]]},"reference":[{"key":"2020062002532933900_ref1","first-page":"1","volume-title":"IEEE Int.
