Relay-Selection Improves the Security-Reliability Trade-Off in Cognitive Radio Systems
TL;DR: It is shown that as the intercept probability requirement is relaxed, the outage performance of the direct transmission, the artificial noise based and the relay selection schemes improves, and vice versa, and the SRTs of the single-relay and multi-relays selection approaches significantly improve.
Journal ArticleDOI
Secure Transmission in Cognitive Satellite Terrestrial Networks
TL;DR: This paper proposes to employ a multi-antenna base station (BS) as a source of green interference to enhance secure transmission in the satellite network and presents two beamforming schemes, namely, hybrid zero- forcing and partial zero-forcing to solve the optimization problem and obtain the BF weight vectors in a closed form.
Journal ArticleDOI
Outage Performance of Cognitive Hybrid Satellite–Terrestrial Networks With Interference Constraint
TL;DR: This paper investigates the performance of a cognitive hybrid satellite-terrestrial network, where the primary satellite communication network and the secondary terrestrial mobile network coexist, provided that the interference temperature constraint is satisfied.
Journal ArticleDOI
A Toeplitz Covariance Matrix Reconstruction Approach for Direction-of-Arrival Estimation
Xiaohuan Wu,Wei-Ping Zhu,Jun Yan +2 more
TL;DR: It is shown that CMRA can be regarded as an atomic norm minimization model or a gridless version of the sparsity-based methods and can recover more signals than sensors with a well-designed array.
Journal ArticleDOI
Joint Beamforming for Secure Communication in Cognitive Satellite Terrestrial Networks
TL;DR: This paper proposes beamforming (BF) schemes to utilize the interference from the terrestrial network as a green source to enhance the physical-layer security for the satellite network, provided that the two networks share the portion of millimeter-wave frequencies.
