This behavior is well-captured by the Two-Wave with Diffuse Power (TWDP) fading distribution, which shows great fit to field measurements in such scenarios. In this paper, we address the joint estimation of the parameters K and \u0394 that characterize the TWDP fading model, based on the observation of the received signal envelope. We use a moment-based approach to derive closed-form expressions for the estimators of K and \u0394, as well as closed-form expressions for their asymptotic variance. Results show that the estimation error is close to the Cramer-Rao lower bound for a wide range of values of the parameters K and \u0394. The performance degradation due to a finite number of observations is also analyzed.<\/jats:p>","DOI":"10.3390\/s16071014","type":"journal-article","created":{"date-parts":[[2016,6,30]],"date-time":"2016-06-30T14:24:28Z","timestamp":1467296668000},"page":"1014","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Joint Parameter Estimation for the Two-Wave with Diffuse Power Fading Model"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3391-9836","authenticated-orcid":false,"given":"Jesus","family":"Lopez-Fernandez","sequence":"first","affiliation":[{"name":"Departamento de Ingenier\u00eda de Comunicaciones, ETS Ingenier\u00eda de Telecomunicaci\u00f3n, Universidad de M\u00e1laga, M\u00e1laga 29071, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laureano","family":"Moreno-Pozas","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda de Comunicaciones, ETS Ingenier\u00eda de Telecomunicaci\u00f3n, Universidad de M\u00e1laga, M\u00e1laga 29071, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0233-6942","authenticated-orcid":false,"given":"Francisco","family":"Lopez-Martinez","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda de Comunicaciones, ETS Ingenier\u00eda de Telecomunicaci\u00f3n, Universidad de M\u00e1laga, M\u00e1laga 29071, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eduardo","family":"Martos-Naya","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda de Comunicaciones, ETS Ingenier\u00eda de Telecomunicaci\u00f3n, Universidad de M\u00e1laga, M\u00e1laga 29071, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2016,6,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Simon, M.K., and Alouini, M.-S.
