Channel, Phase Noise, and Frequency Offset in OFDM Systems: Joint Estimation, Data Detection, and Hybrid Cramer-Rao Lower Bound
Omar H. Salim, Ali A. Nasir, Hani Mehrpouyan +3
Oscillator phase noise (PHN) and carrier frequency offset (CFO) can adversely impact the performance of orthogonal frequency division multiplexing (OFDM) systems, since they can re…
Structured Optimal Transmission Control in Network-coded Two-way Relay Channels
Ni Ding, Parastoo Sadeghi, Rodney A. Kennedy
This paper considers a transmission control problem in network-coded two-way relay channels (NC-TWRC), where the relay buffers random symbol arrivals from two users, and the channe…
Wireless-Powered Relays in Cooperative Communications: Time-Switching Relaying Protocols and Throughput Analysis
Ali Arshad Nasir, Xiangyun Zhou, Salman Durrani +1
We consider wireless-powered amplify-and-forward and decode-and-forward relaying in cooperative communications, where an energy constrained relay node first harvests energy through…
Training-Based Synchronization and Channel Estimation in AF Two-Way Relaying Networks
Ali Arshad Nasir, Hani Mehrpouyan, Salman Durrani +2
Two-way relaying networks (TWRNs) allow for more bandwidth efficient use of the available spectrum since they allow for simultaneous information exchange between two users with the…
Spatio-spectral Formulation and Design of Spatially-Varying Filters for Signal Estimation on the 2-Sphere
Zubair Khalid, Rodney A. Kennedy, Parastoo Sadeghi +1
In this paper, we present an optimal filter for the enhancement or estimation of signals on the 2-sphere corrupted by noise, when both the signal and noise are realizations of anis…
Classification and construction of closed-form kernels for signal representation on the 2-sphere
Rodney A. Kennedy, Parastoo Sadeghi, Zubair Khalid +1
This paper considers the construction of Reproducing Kernel Hilbert Spaces (RKHS) on the sphere as an alternative to the conventional Hilbert space using the inner product that yie…
