In this paper, we proposed and investigated energy harvesting (EH) based two-way half-duplex (TWHD) relaying sensors network using selection combining (SC) over block Rayleigh fading channel. In this model, we proposed the direct link between two sources for improving the system performance. For the system performance analysis, we investigated and derived the closed-form of the exact and upper bound Ergodic capacity (EC) and the exact form of the symbol error ratio (SER). By using the Monte Carlo simulation, the correctness of the research results is verified in the influence of the main system parameters. From the discussions, we can see that the analytical and simulation agree well with each other.<\/jats:p>","DOI":"10.3390\/s20041165","type":"journal-article","created":{"date-parts":[[2020,2,21]],"date-time":"2020-02-21T10:49:16Z","timestamp":1582282156000},"page":"1165","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Exploiting Direct Link in Two-Way Half-Duplex Sensor Network over Block Rayleigh Fading Channel: Upper Bound Ergodic Capacity and Exact SER Analysis"],"prefix":"10.3390","volume":"20","author":[{"given":"Phu Tran","family":"Tin","sequence":"first","affiliation":[{"name":"IT4Innovations ,VSB-Technical University of Ostrava, 70833 Ostrava, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2286-6652","authenticated-orcid":false,"given":"Tan N.","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Wireless Communications Research Group, Faculty of Electrical and Electronics Engineering, Ton Duc Thang University, Ho Chi Minh City 70000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2956-6206","authenticated-orcid":false,"given":"Minh","family":"Tran","sequence":"additional","affiliation":[{"name":"Optoelectronics Research Group, Faculty of Electrical and Electronics Engineering, Ton Duc Thang University, Ho Chi Minh City 70000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tran Thanh","family":"Trang","sequence":"additional","affiliation":[{"name":"Faculty of Electrical and Electronics Engineering, Ho Chi Minh City University of Food Industry, 140 Le Trong Tan, Ho Chi Minh City 70000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lukas","family":"Sevcik","sequence":"additional","affiliation":[{"name":"IT4Innovations ,VSB-Technical University of Ostrava, 70833 Ostrava, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"117","DOI":"10.1109\/MCOM.2015.7081084","article-title":"Wireless powered communication: Opportunities and challenges","volume":"53","author":"Bi","year":"2015","journal-title":"IEEE Commun.
