For this system, it is hard to obtain a closed\u2010form expression for the moment generating function (MGF) of the end\u2010to\u2010end signal\u2010to\u2010noise ratio (SNR) at the destination, even for the case of a single dual\u2010hop relay link. Therefore, we employ two different upper bound approximations for the output SNR, of which one is based on the minimum SNR of the two hops for each dual\u2010hop relay link and the other is based on the geometric mean of the SNRs of the two hops. Lower bounds for the symbol and bit error rates for a variety of digital modulations can then be evaluated using the MGF\u2010based approach. The final expressions are useful in the performance evaluation of amplify\u2010and\u2010forward relaying in a generalized composite radio environment.<\/jats:p>","DOI":"10.1155\/2010\/584594","type":"journal-article","created":{"date-parts":[[2010,6,9]],"date-time":"2010-06-09T14:34:33Z","timestamp":1276094073000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["On the Error Rate Analysis of Dual\u2010Hop Amplify\u2010and\u2010Forward Relaying in Generalized\u2010<i>K<\/i> Fading Channels"],"prefix":"10.1155","volume":"2010","author":[{"given":"George P.","family":"Efthymoglou","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nikolaos","family":"Bissias","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valentine A.","family":"Aalo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2010,6,9]]},"reference":[{"key":"e_1_2_6_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2003.819030"},{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/TCOMM.2003.822185"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1049\/el:20040393"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/LCOM.2007.348292"},{"key":"e_1_2_6_5_2","doi-asserted-by":"crossref","unstructured":"IkkiS.
