In this paper, we address the channel measurement for link reliability evaluation in filter\u2010bank multicarrier with offset quadrature amplitude modulation\u2010 (FBMC\/OQAM\u2010) based IoT network, which is considered as a promising technique for future wireless communications. However, resulting from the imaginary interference and the noise correlation among subcarriers in FBMC\/OQAM, the existing frequency correlation method cannot be directly applied in the FBMC\/OQAM\u2010based IoT network. In this study, the concept of the block repetition is applied in FBMC\/OQAM. It is demonstrated that the noises among subcarriers are independent by the block repetition and linear combination, instead of correlated. On this basis, the classical frequency correlation method can be applied to achieve the channel measurement. Then, we also propose an advanced frequency correlation method to improve the accuracy of the channel measurement, by assuming channel frequency responses to be quasi\u2010invariant for several successive subcarriers. Simulations are conducted to validate the proposed schemes.<\/jats:p>","DOI":"10.1155\/2022\/6518066","type":"journal-article","created":{"date-parts":[[2022,1,10]],"date-time":"2022-01-10T18:35:11Z","timestamp":1641839711000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Channel Measurement and Noise Estimation in FBMC\/OQAM\u2010Based IoT Networks"],"prefix":"10.1155","volume":"2022","author":[{"given":"Jun","family":"Sun","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaomin","family":"Mu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7119-9895","authenticated-orcid":false,"given":"Dejin","family":"Kong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,1,10]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.1002\/9780470742891"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/TIM.2015.2477166"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/TCOMM.2020.3025294"},{"key":"e_1_2_10_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/TII.2020.2995598"},{"key":"e_1_2_10_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/JSAC.2017.2710022"},{"key":"e_1_2_10_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2020.2971185"},{"key":"e_1_2_10_7_2","volume-title":"Alamouti Code Based on Block Repetition in FBMC\/OQAM Systems","author":"Kong D.","year":"2021"},{"key":"e_1_2_10_8_2","unstructured":"3GPP Evolved Universal Terrestrial Radio Access (E-UTRA); Physical layer; Measurements 2011 http:\/\/www.3gpp.org\/ftp\/Specs\/archive\/36_series\/36.214\/36214-a30.zip."},{"key":"e_1_2_10_9_2","doi-asserted-by":"crossref","unstructured":"HuangG.
