As shown in this paper, PAPR becomes even severe for sparse source due to many identical nonzero frequency OFDM symbols. Thus, this paper introduces compressive coded modulation (CCM) in order to restrain PAPR by reducing identical nonzero frequency symbols for sparse source. As a result, the proposed CCM\u2010based OFDM system, together with iterative clipping and filtering, can efficiently restrain the high PAPR for sparse source. Simulation results show that it outperforms about 4\u2009dB over the traditional OFDM system when source sparsity is 0.1.<\/jats:p>","DOI":"10.1155\/2018\/8923478","type":"journal-article","created":{"date-parts":[[2018,3,21]],"date-time":"2018-03-21T23:32:34Z","timestamp":1521675154000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A CCM\u2010Based OFDM System with Low PAPR for Sparse Source"],"prefix":"10.1155","volume":"2018","author":[{"given":"Qinbiao","family":"Yang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zulin","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8717-254X","authenticated-orcid":false,"given":"Qin","family":"Huang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,3,21]]},"reference":[{"key":"e_1_2_8_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/tcom.1985.1096357"},{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/35.54342"},{"key":"e_1_2_8_3_2","doi-asserted-by":"crossref","unstructured":"RuC.
