Compressive Direction Finding Based on Amplitude Comparison
Ruiming Yang, Yipeng Liu, Qun Wan +1
This paper exploits recent developments in compressive sensing (CS) to efficiently perform the direction finding via amplitude comprarison. The new method is proposed based on unim…
Enhanced Compressive Wideband Frequency Spectrum Sensing for Dynamic Spectrum Access
Yipeng Liu, Qun Wan
Wideband spectrum sensing detects the unused spectrum holes for dynamic spectrum access (DSA). Too high sampling rate is the main problem. Compressive sensing (CS) can reconstruct…
Inter-atom Interference Mitigation for Sparse Signal Reconstruction Using Semi-blindly Weighted Minimum Variance Distortionless Response
Ruiming Yang, Qun Wan, Yipeng Liu +1
The feasibility of sparse signal reconstruction depends heavily on the inter-atom interference of redundant dictionary. In this paper, a semi-blindly weighted minimum variance dist…
Anti-measurement Matrix Uncertainty Sparse Signal Recovery for Compressive Sensing
Yipeng Liu, Qun Wan, Fei Wen +2
Compressive sensing (CS) is a technique for estimating a sparse signal from the random measurements and the measurement matrix. Traditional sparse signal recovery methods have seri…
A Robust Beamformer Based on Weighted Sparse Constraint
Yipeng Liu, Qun Wan, Xiaoli Chu
Applying a sparse constraint on the beam pattern has been suggested to suppress the sidelobe level of a minimum variance distortionless response (MVDR) beamformer. In this letter,…
Improved OMP Approach to Sparse Multi-path Channel Estimation via Adaptive Inter-atom Interference Mitigation
Ruiming Yang, Qun Wan, Yipeng Liu +1
Since most components of sparse multi-path channel (SMPC) are zero, impulse response of SMPC can be recovered from a short training sequence. Though the ordinary orthogonal matchin…
