However, its conventional parameterization based on parameters K and \u0394 is not in line with model\u2019s underlying physical mechanisms. Accordingly, in this paper, we first identified anomalies related to usage of conventional TWDP parameterization in moment-based estimation, showing that the existing \u0394-based estimators are unable to provide meaningful estimates in some channel conditions. Then, we derived moment-based estimators of recently introduced physically justified TWDP parameters K and \u0393 and analyzed their performance through asymptotic variance (AsV) and Cramer\u2013Rao bound (CRB) metrics. Performed analysis has shown that \u0393-based estimators managed to overcome all anomalies observed for \u0394-based estimators, simultaneously improving the overall moment-based estimation accuracy.<\/jats:p>","DOI":"10.3390\/s22030774","type":"journal-article","created":{"date-parts":[[2022,1,20]],"date-time":"2022-01-20T22:51:06Z","timestamp":1642719066000},"page":"774","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Moment-Based Parameter Estimation for the \u0393-Parameterized TWDP Model"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3005-3934","authenticated-orcid":false,"given":"Pamela","family":"Njemcevic","sequence":"first","affiliation":[{"name":"Department of Telecommunications, Faculty of Electrical Engineering, University of Sarajevo, Zmaja od Bosne b.b., Kampus Univerziteta, 71000 Sarajevo, Bosnia and Herzegovina"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1902-2608","authenticated-orcid":false,"given":"Enio","family":"Kaljic","sequence":"additional","affiliation":[{"name":"Department of Telecommunications, Faculty of Electrical Engineering, University of Sarajevo, Zmaja od Bosne b.b., Kampus Univerziteta, 71000 Sarajevo, Bosnia and Herzegovina"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5912-2967","authenticated-orcid":false,"given":"Almir","family":"Maric","sequence":"additional","affiliation":[{"name":"Department of Telecommunications, Faculty of Electrical Engineering, University of Sarajevo, Zmaja od Bosne b.b., Kampus Univerziteta, 71000 Sarajevo, Bosnia and Herzegovina"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1794","DOI":"10.1109\/TWC.2013.030413.120772","article-title":"Performance of QAM signaling over TWDP fading channels","volume":"12","author":"Dixit","year":"2013","journal-title":"IEEE Trans.
