In this paper we present analytical performance evaluation of a dual-hop OFDM amplify-andforward (AF) variable gain (VG) relay system implementing ordered subcarrier mapping (SCM) at the relay station (R). considered to be a very interesting solution for the next generation mobile cellular networks. A scenario with no direct communication between the source of information (S) and dest... https://www.ngetikin.com/limited-buy-LA-Williams-Belial-Dragon-by-LA-Williams-Google-Pixel-2-Skin-p114135-best-save/
