On the target secrecy rate for SISOME wiretap channels
2014 IEEE International Conference on Communications (ICC), 2014We propose a new framework for optimizing the target secrecy rate for SISOME wiretap channels when the instantaneous capacity of the eavesdropper's channel is not available at the transmitter. In our framework we introduce the effective secrecy throughput, a new optimization metric that implicitly captures the two key features of wiretap channels ...

Secrecy Rates for Relay Selection in OFDMA Networks
2011 Third International Conference on Communications and Mobile Computing, 2011In this paper, we study the secrecy communication using physical layer security in OFDMA networks. The expressions of secrecy rates and outage probability are derived in OFDMA networks using Decode-and-Forward (DF) strategy. Monte Carlo simulations are carried out to validate our analysis.

Weighted Sum Secrecy Rate Maximization for D2D Underlaid Cellular Networks
IEEE Transactions on Communications, 2020This paper investigates the secrecy rate performance of a device-to-device (D2D) underlaid cellular network with an eavesdropper. Both the base station (BS) and the eavesdropper are assumed to have multiple antennas and apply minimum mean-square error ...

Secrecy Rate of Time Switched Transmit Diversity System
2011 IEEE 73rd Vehicular Technology Conference (VTC Spring), 2011Time switched transmit diversity (TSTD) system uses only one out of several transmit antennas at a time in order to exploit the benefit of transmit diversity while keeping the system simple by having only one RF chain. We show that while average rate of such a system remains similar to the capacity of the single transmit antenna, outage secrecy ...

Robust Beamforming Design for Sum Secrecy Rate Maximization in Multibeam Satellite Systems
IEEE Transactions on Aerospace and Electronic Systems, 2019This letter investigates the secure transmission optimization in a multibeam satellite downlink network with multiple eavesdroppers, where each legitimate user is wiretapped by a corresponding eavesdropper.

Secrecy Rate Maximization via Radio Resource Allocation in Cellular Underlaying V2V Communications
IEEE Transactions on Vehicular Technology, 2020In device-to-device (D2D) underlaying vehicle-to-vehicle (V2V) communications, radio resource blocks (RBs) are allocated to primary cellular users, which yields sub-optimal rates and a long access latency for secondary D2D-enabled vehicles.

Achievable Secrecy Rate Region for Buffer-Aided Multiuser MISO Systems
IEEE Transactions on Information Forensics and Security, 2020In this paper, we consider a buffer-aided multiuser multiple-input single-output (MISO) network consisting of one multi-antenna access point (AP) and multiple single-antenna users, in which the AP is provisioned with data buffers for temporarily storing ...

Antenna Selection Method of Maximizing Secrecy Rate for Green Secure Spatial Modulation
IEEE Transactions on Green Communications and Networking, 2019In secure spatial modulation systems, an active antenna-group (AAG) selection of maximizing the average secrecy rate (SR) is proposed to avoid the disadvantage that conventional AAG selection scheme of minimizing bit error ratio at desired receiver may ...
