In particular, the outage probability is derived in the closed-form expressions under the opportunistic partial relay selection. Different from the conventional CRNs in which the transmit power of the secondary transmitters count merely on the aggregate interference measured on the primary networks, the transmit power of the SWIPT-enabled transmitters is also constrained by the harvested energy. As a result, the mathematical framework involves more correlated random variables and, thus, is of higher complexity. Monte Carlo simulations are given to corroborate the accuracy of the mathematical analysis and to shed light on the behavior of the OP with respect to several important parameters, e.g., the transmit power and the number of relays. Our findings illustrate that increasing the transmit power and\/or the number of relays is beneficial for the outage probability.<\/jats:p>","DOI":"10.3390\/s21227653","type":"journal-article","created":{"date-parts":[[2021,11,19]],"date-time":"2021-11-19T02:43:09Z","timestamp":1637289789000},"page":"7653","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Outage Analysis of the Power Splitting Based Underlay Cooperative Cognitive Radio Networks"],"prefix":"10.3390","volume":"21","author":[{"given":"Phu Tran","family":"Tin","sequence":"first","affiliation":[{"name":"Faculty of Electronics Technology, Industrial University of Ho Chi Minh City, Ho Chi Minh City 700000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4470-5160","authenticated-orcid":false,"given":"Van-Duc","family":"Phan","sequence":"additional","affiliation":[{"name":"Faculty of Automobile Technology, Van Lang University, Ho Chi Minh City 700000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2286-6652","authenticated-orcid":false,"given":"Tan N.","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Communication and Signal Processing Research Group, Faculty of Electrical and Electronics Engineering, Ton Duc Thang University, Ho Chi Minh City 700000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lam-Thanh","family":"Tu","sequence":"additional","affiliation":[{"name":"Institute XLIM, University of Poitiers, 86000 Poitiers, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0222-166X","authenticated-orcid":false,"given":"Bui Vu","family":"Minh","sequence":"additional","affiliation":[{"name":"Faculty of Automotive, Mechanical, Electrical and Electronic Engineering, Nguyen Tat Thanh University, Ho Chi Minh City 700000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5135-7980","authenticated-orcid":false,"given":"Miroslav","family":"Voznak","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering and Computer Science, VSB-Technical University of Ostrava, 708 00 Ostrava, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peppino","family":"Fazio","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering and Computer Science, VSB-Technical University of Ostrava, 708 00 Ostrava, Czech Republic"},{"name":"Department of Molecular Sciences and Nanosystems, Ca\u2019 Foscari University of Venice, Via Torino 155, 30123 Venezia VE, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Yu, H., and Zikria, Y.B.
