We point out that there are differences in correlation characteristics between the conventional and time-reversed chaotic sequences. From this aspect, bit-error-rate (BER) performance of the system over an additive white Gaussian noise (AWGN) channel is analyzed taking into account the correlation effect of time-reversed chaotic sequences. BER expressions are verified by Monte-Carlo simulation. The obtained results prove that the 2T2R-IDCSK system performs worse under the correlation effect, however still dramatically outperforms the conventional [Formula: see text] MIMO-DCSK system. <\/jats:p>","DOI":"10.1142\/s0218127421500693","type":"journal-article","created":{"date-parts":[[2021,5,5]],"date-time":"2021-05-05T06:29:43Z","timestamp":1620196183000},"page":"2150069","source":"Crossref","is-referenced-by-count":2,"title":["Effect of Time-Reversed Chaotic Sequences on the Performance of 2T2R-IDCSK System"],"prefix":"10.1142","volume":"31","author":[{"given":"Doan Thi","family":"Que","sequence":"first","affiliation":[{"name":"Hanoi University of Science and Technology, No. 1 Dai Co Viet, Hai Ba Trung, Hanoi, Vietnam"},{"name":"Thuyloi University, No. 175 Tay Son, Dong Da, Hanoi, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nguyen Xuan","family":"Quyen","sequence":"additional","affiliation":[{"name":"Hanoi University of Science and Technology, No. 1 Dai Co Viet, Hai Ba Trung, Hanoi, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thang Manh","family":"Hoang","sequence":"additional","affiliation":[{"name":"Hanoi University of Science and Technology, No. 1 Dai Co Viet, Hai Ba Trung, Hanoi, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christos","family":"Volos","sequence":"additional","affiliation":[{"name":"Department of Physics, Aristotle University of Thessaloniki, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stevan","family":"Berber","sequence":"additional","affiliation":[{"name":"ECSE Department, The University of Auckland, New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2021,4,29]]},"reference":[{"key":"S0218127421500693BIB001","doi-asserted-by":"publisher","DOI":"10.1109\/49.730453"},{"key":"S0218127421500693BIB002","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2005.847304"},{"key":"S0218127421500693BIB003","doi-asserted-by":"publisher","DOI":"10.1109\/TCOMM.2016.2538236"},{"key":"S0218127421500693BIB005","doi-asserted-by":"publisher","DOI":"10.1016\/0375-9601(84)90993-9"},{"key":"S0218127421500693BIB006","first-page":"1114","volume":"51","author":"He B.","year":"2018","journal-title":"Engin.
