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…
Sparse Multipath Channel Estimation Using Compressive Sampling Matching Pursuit Algorithm
Guan Gui, Qun Wan, Wei Peng +1
Wideband wireless channel is a time dispersive channel and becomes strongly frequency-selective. However, in most cases, the channel is composed of a few dominant taps and a large…
Sparse Multipath Channel Estimation using DS Algorithm in Wideband Communication Systems
Guan Gui, An-min Huang, Qun Wan
Wideband wireless channel is a time dispersive channel and becomes strongly frequency-selective. However, in most cases, the channel is composed of a few dominant taps and a large…
A Fast Compressive Channel Estimation with Modified Smoothed L0 Algorithm
Guan Gui, Wei Peng, Qun Wan +1
Broadband wireless channel is a time dispersive and becomes strongly frequency selective. In most cases, the channel is composed of a few dominant coefficients and a large part of…
Compressive Wideband Spectrum Sensing for Fixed Frequency Spectrum Allocation
Yipeng Liu, Qun Wan
Too high sampling rate is the bottleneck to wideband spectrum sensing for cognitive radio (CR). As the survey shows that the sensed signal has a sparse representation in frequency…
