OFDMA-based DF Secure Cooperative Communication with Untrusted Users

11 Jan 2019 Saini Ravikant Mishra Deepak De Swades

In this letter we consider resource allocation for OFDMA-based secure cooperative communication by employing a trusted Decode and Forward (DF) relay among the untrusted users. We formulate two optimization problems, namely, (i) sum rate maximization subject to individual power constraints on source and relay, and (ii) sum power minimization subject to a fairness constraint in terms of per-user minimum support secure rate requirement...
