Utility Regions for DF Relay in OFDMA-based Secure Communication with Untrusted Users
Ravikant Saini, Deepak Mishra, Swades De
This paper investigates the utility of a trusted decode-and-forward relay in OFDMA-based secure communication system with untrusted users. For deciding whether to use the relay or…
Subcarrier Pairing as Channel Gain Tailoring: Joint Resource Allocation for Relay-Assisted Secure OFDMA with Untrusted Users
Ravikant Saini, Deepak Mishra, Swades De
Joint resource allocation involving optimization of subcarrier allocation, subcarrier pairing (SCP), and power allocation in a cooperative secure orthogonal frequency division mult…
Jammer-Assisted Resource Allocation in Secure OFDMA With Untrusted Users
Ravikant Saini, Abhishek Jindal, Swades De
In this paper, we consider the problem of resource allocation in the orthogonal frequency division multiple access system with single source and M untrusted users in presence of a…
OFDMA-based DF Secure Cooperative Communication with Untrusted Users
Ravikant Saini, Deepak Mishra, Swades De
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 f…
