The considered dual\u2010hop system consists of a radio frequency (RF) link followed by a free space optical (FSO) channel. The RF link is affected by short\u2010term multipath fading and long\u2010term shadowing effects and is assumed to follow the generalized\u2010<jats:italic>K<\/jats:italic> fading distribution that approximates accurately several important distributions often used to model communication channels. The FSO channel experiences fading caused by atmospheric turbulence that is modeled by the gamma\u2010gamma distribution characterizing moderate and strong turbulence conditions. The FSO channel also suffers path loss and pointing error induced misalignment fading. The performance of the considered system is analyzed under the collective influence of distribution shaping parameters, pointing errors that result in misalignment fading, atmospheric turbulence, and path loss. The moment\u2010generating function of the Signal power to noise power ratio measured end\u2010to\u2010end for this system is derived. The cumulative distribution function for the Signal power to noise power ratio present between the source and destination receiver is also evaluated. Further, we investigate the error and outage performance and the average channel capacity for this system. The analytical expressions in closed form for the outage probability, symbol and bit error rate considering different modulation schemes and channel capacity are also derived. The mathematical expressions obtained are also demonstrated by numerical plots.<\/jats:p>","DOI":"10.1002\/dac.3400","type":"journal-article","created":{"date-parts":[[2017,8,24]],"date-time":"2017-08-24T01:43:00Z","timestamp":1503538980000},"source":"Crossref","is-referenced-by-count":17,"title":["Performance analysis of a variable\u2010gain amplify\u2010and\u2010forward relayed mixed RF\u2010FSO system"],"prefix":"10.1002","volume":"31","author":[{"given":"Himanshu","family":"Khanna","sequence":"first","affiliation":[{"name":"Department of EECE The Northcap University  Gurugram, Haryana India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3295-9764","authenticated-orcid":false,"given":"Mona","family":"Aggarwal","sequence":"additional","affiliation":[{"name":"Department of EECE The Northcap University  Gurugram, Haryana India"}]},{"given":"Swaran","family":"Ahuja","sequence":"additional","affiliation":[{"name":"Department of EECE The Northcap University  Gurugram, Haryana India"}]}],"member":"311","published-online":{"date-parts":[[2017,8,23]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/JSAC.2014.2328098"},{"issue":"1","key":"e_1_2_9_3_1","first-page":"1","article-title":"Mixed mmWave RF\/FSO relaying systems over generalized fading channels with pointing errors","volume":"9","author":"Trinh PV","year":"2017","journal-title":"IEEE J Photon"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1109\/JLT.2006.885252"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1117\/3.412858"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1049\/iet-com.2010.0172"},{"key":"e_1_2_9_7_1","doi-asserted-by":"crossref","unstructured":"SaquibN SakibMSR SahaA HussainM.Free space optical connectivity for last mile solution in Bangladesh.
