We present a cyclically closed constant-envelope orthogonal time frequency space\u2013continuous phase modulation\u2013linear frequency modulation (OTFS\u2013CPM\u2013LFM) waveform and matched transceiver architecture. Hermitian delay\u2013Doppler mapping and direct-current (DC) row nulling create a real, zero-sum drive with a reversible frame-level phase representation. The communication receiver combines a Tikhonov-regularized waveform inverse with reference-aided unwrapping and tail-biting phase regression, while the radar receiver reconstructs the data-dependent current-frame reference. Numerical results verify the structural waveform properties and characterize communication, radar, and computational tradeoffs. They also quantify degradation under controlled complex-gain channel-state-information mismatch and show that phase regression is less reliable at a low signal-to-noise ratio (SNR). The constant-envelope claim applies only to ideal discrete complex-baseband samples and does not include pulse shaping or radio-frequency hardware. The framework therefore provides a self-consistent waveform interface while exposing tradeoffs among payload, recovery reliability, sensing sidelobes, and implementation cost.<\/jats:p>","DOI":"10.3390\/s26165130","type":"journal-article","created":{"date-parts":[[2026,8,13]],"date-time":"2026-08-13T17:01:35Z","timestamp":1786640495000},"page":"5130","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Constant-Envelope Waveform Design and Phase Recovery for Integrated Sensing and Communication in High-Mobility Multipath Environments"],"prefix":"10.3390","volume":"26","author":[{"given":"Wenhui","family":"Xue","sequence":"first","affiliation":[{"name":"School of Information Science and Engineering, Southeast University, Nanjing 210096, China"},{"name":"Jiang Nan Design & Research Institute of Machinery & Electricity, Guiyang 550000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7120-1577","authenticated-orcid":false,"given":"Peng","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Millimeter Waves, Southeast University, Nanjing 210096, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chunguo","family":"Li","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Southeast University, Nanjing 210096, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenxin","family":"Cao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Millimeter Waves, Southeast University, Nanjing 210096, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuqin","family":"Zhang","sequence":"additional","affiliation":[{"name":"Jiang Nan Design & Research Institute of Machinery & Electricity, Guiyang 550000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3834","DOI":"10.1109\/TCOMM.2020.2973976","article-title":"Joint Radar and Communication Design: Applications, State-of-the-Art, and the Road Ahead","volume":"68","author":"Liu","year":"2020","journal-title":"IEEE Trans.
