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…
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…
Error Performance Analysis of DF and AF Multi-way Relay Networks with BPSK Modulation
Shama N. Islam, Parastoo Sadeghi, Salman Durrani
In this paper, we analyze the error performance of decode and forward (DF) and amplify and forward (AF) multi-way relay networks (MWRN). We consider a MWRN with pair-wise data exch…
Outage Probability in Arbitrarily-Shaped Finite Wireless Networks
Jing Guo, Salman Durrani, Xiangyun Zhou
This paper analyzes the outage performance in finite wireless networks. Unlike most prior works, which either assumed a specific network shape or considered a special location of t…
