By utilizing the intrinsicsparsity of wireless channels, channel estimation is researched as a compressive sensing (CS) problem to improve the estimation performance. In this paper, an AdaptiveRegularized Compressive Sampling Matching Pursuit (ARCoSaMP) algorithm is proposed. Unlike anterior greedy algorithms, the new algorithm can achieve the accuracy of reconstruction by choosing the support set adaptively, and exploiting the regularization process, which realizes the second selecting of atoms in the support set although the sparsity of the channel is unknown. Simulation results show that CS-based methods obtain significant channel estimation performance improvement compared to that of conventional preamble-based methods. The proposed ARCoSaMP algorithm outperforms the conventional sparse adaptive matching pursuit (SAMP) algorithm. ARCoSaMP provides even more interesting results than the mostadvanced greedy compressive sampling matching pursuit (CoSaMP) algorithm without a prior sparse knowledge of the channel.<\/jats:p>","DOI":"10.3390\/s16070966","type":"journal-article","created":{"date-parts":[[2016,6,25]],"date-time":"2016-06-25T21:21:45Z","timestamp":1466889705000},"page":"966","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["A New Sparse Adaptive Channel Estimation Method Based on Compressive Sensing for FBMC\/OQAM Transmission Network"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7347-3763","authenticated-orcid":false,"given":"Han","family":"Wang","sequence":"first","affiliation":[{"name":"College of Information Science &amp; Technology, Hainan University, Haikou 570228, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wencai","family":"Du","sequence":"additional","affiliation":[{"name":"College of Information Science &amp; Technology, Hainan University, Haikou 570228, China"},{"name":"Faculty of International Tourism and Management, City University of Macau, Macau 999078, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2169-6356","authenticated-orcid":false,"given":"Lingwei","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Information Science &amp; Technology, Qingdao University of Science &amp; Technology, Qingdao 266061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2016,6,24]]},"reference":[{"key":"ref_1","unstructured":"FP7-ICT PHYDYAS Project Prototype Filter and Structure Optimization, Project Deliverable D5.1, (Section 5.2.3).
