The main reason for using Reed\u2013Muller and Polar codes is to protect the information bits to be transmitted while providing error correction capability and improved PAPR performance to the transmitted signal. Although OFDM-IM technology is a popular communication transmission technology recently, one of its disadvantages is that the transmitted signal has a high PAPR. The proposed method uses the Hamming weight distribution of the specific order Reed\u2013Muller code to create a corresponding lookup table to select the subcarriers that are active in the OFDM-IM system. Moreover, it can correct errors in the information used. The proposed method also uses Polar codes as a channel encoder of the OFDM-IM system to analyze its performance in improving the PAPR. The simulation results show that method can not only improve the PAPR performance of OFDM-IM systems but also provide OFDM-IM transmission-signal error correction capacity.<\/jats:p>","DOI":"10.12720\/jcm.18.1.76-81","type":"journal-article","created":{"date-parts":[[2023,2,22]],"date-time":"2023-02-22T02:41:21Z","timestamp":1677033681000},"page":"76-81","source":"Crossref","is-referenced-by-count":2,"title":["A Modified Selective Mapping Technique for Peak-to-Average Power Ratio Reduction in Orthogonal Frequency Division Multiplexing with Index Modulation Systems"],"prefix":"10.12720","author":[{"name":"Dept. of Information and Communication Engineering, Chaoyang University of Technology, Taichung, Taiwan","sequence":"first","affiliation":[]},{"given":"Hsiu-Wen","family":"Liu","sequence":"first","affiliation":[]},{"given":"Hsin-Ying","family":"Liang","sequence":"additional","affiliation":[]}],"member":"4977","published-online":{"date-parts":[[2023]]},"container-title":["Journal of Communications"],"original-title":[],"link":[{"URL":"http:\/\/www.jocm.us\/2023\/JCM-V18N1-76.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,2,22]],"date-time":"2023-02-22T02:41:28Z","timestamp":1677033688000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.jocm.us\/show-281-1859-1.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023]]},"references-count":0,"URL":"https:\/\/doi.org\/10.12720\/jcm.18.1.76-81","relation":{},"ISSN":["2374-4367"],"issn-type":[{"type":"print","value":"2374-4367"}],"subject":[],"published":{"date-parts":[[2023]]}}}
