In the presented system, one of a constellation pair is the same as the one used in the previous work, and the other is a constellation larger than the one used in the previous work. It increases the minimum Euclidean distance between the subblocks of the ZTM-OFDM-IM system with new constellation pairs under the constraint of the same spectral efficiency. Computer simulation in AWGN and frequency-selective fading channels shows that the new ZTM-OFDM-IM system has a much lower bit error rate than OFDM-IM and dual-mode OFDM-IM and slightly outperforms the system with conventional constellation pairs. Since the proposed constellation pairs prove the error performance improvement of the system, it is considered that a further study on generalized design of the constellation pair for the ZTM-OFDM-IM system is necessary in the future.<\/jats:p>","DOI":"10.1155\/2020\/8816655","type":"journal-article","created":{"date-parts":[[2020,8,1]],"date-time":"2020-08-01T23:35:28Z","timestamp":1596324928000},"page":"1-7","source":"Crossref","is-referenced-by-count":0,"title":["New Signal Constellation Pairs for the ZTM-OFDM-IM System"],"prefix":"10.1155","volume":"2020","author":[{"given":"Shuang","family":"Li","sequence":"first","affiliation":[{"name":"Department of Electrical and Electronic Engineering, Gyeongsang National University, Jinju, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5329-3551","authenticated-orcid":true,"given":"Seog Geun","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Semiconductor Engineering and the Engineering Research Institute, Gyeongsang National University, Jinju, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"doi-asserted-by":"publisher","key":"1","DOI":"10.1109\/JSAC.2014.141203"},{"doi-asserted-by":"publisher","key":"2","DOI":"10.1145\/2534169.2486039"},{"doi-asserted-by":"publisher","key":"3","DOI":"10.1109\/MCOM.2009.4907406"},{"doi-asserted-by":"publisher","key":"4","DOI":"10.1109\/MCOM.2005.1391513"},{"doi-asserted-by":"publisher","key":"6","DOI":"10.1109\/ACCESS.2017.2737528"},{"doi-asserted-by":"publisher","key":"7","DOI":"10.1109\/COMST.2018.2858567"},{"doi-asserted-by":"publisher","key":"10","DOI":"10.1109\/TSP.2013.2279771"},{"doi-asserted-by":"publisher","key":"11","DOI":"10.1109\/TWC.2017.2702618"},{"doi-asserted-by":"publisher","key":"12","DOI":"10.1109\/TWC.2015.2436925"},{"doi-asserted-by":"publisher","key":"13","DOI":"10.1109\/ACCESS.2016.2601648"},{"doi-asserted-by":"publisher","key":"14","DOI":"10.1109\/ACCESS.2017.2756659"}],"container-title":["Wireless Communications and Mobile Computing"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2020\/8816655.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2020\/8816655.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2020\/8816655.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,8,1]],"date-time":"2020-08-01T23:35:29Z","timestamp":1596324929000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/wcmc\/2020\/8816655\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,8,1]]},"references-count":11,"alternative-id":["8816655","8816655"],"URL":"https:\/\/doi.org\/10.1155\/2020\/8816655","relation":{},"ISSN":["1530-8669","1530-8677"],"issn-type":[{"type":"print","value":"1530-8669"},{"type":"electronic","value":"1530-8677"}],"subject":[],"published":{"date-parts":[[2020,8,1]]}}}
