Approximate Message Passing with Random Initialization for Phase Retrieval
Yuchen Chen, Yandi Shen, Xingyu Xu
We analyze approximate message passing (AMP) with an independent Gaussian initialization for noiseless phase retrieval in the proportional asymptotic regime. A random initializatio…
The Power of Preconditioning in Overparameterized Low-Rank Matrix Sensing
Xingyu Xu, Yandi Shen, Yuejie Chi +1
We propose $\textsf{ScaledGD($λ$)}$, a preconditioned gradient descent method to tackle the low-rank matrix sensing problem when the true rank is unknown, and when the matrix is po…
Phase Transitions in Frequency Agile Radar Using Compressed Sensing
Yuhan Li, Tianyao Huang, Xingyu Xu +2
FAR has improved anti-jamming performance over traditional pulse-Doppler radars under complex electromagnetic circumstances. To reconstruct the range-Doppler information in FAR, ma…
MAJoRCom: A Dual-Function Radar Communication System Using Index Modulation
Tianyao Huang, Nir Shlezinger, Xingyu Xu +2
Dual-function radar communication (DFRC) systems implement both sensing and communication using the same hardware. Such schemes are often more efficient in terms of size, power, an…
Lower Bound for RIP Constants and Concentration of Sum of Top Order Statistics
Gen Li, Xingyu Xu, Yuantao Gu
Restricted Isometry Property (RIP) is of fundamental importance in the theory of compressed sensing and forms the base of many exact and robust recovery guarantees in this field. A…
Multi-Carrier Agile Phased Array Radar
Tianyao Huang, Nir Shlezinger, Xingyu Xu +3
Modern radar systems are expected to operate reliably in congested environments. A candidate technology for meeting these demands is frequency agile radar (FAR), which randomly cha…
Unraveling the Veil of Subspace RIP Through Near-Isometry on Subspaces
Xingyu Xv, Gen Li, Yuantao Gu
Dimensionality reduction is a popular approach to tackle high-dimensional data with low-dimensional nature. Subspace Restricted Isometry Property, a newly-proposed concept, has pro…
Analysis of Frequency Agile Radar via Compressed Sensing
Tianyao Huang, Yimin Liu, Xingyu Xu +2
Frequency agile radar (FAR) is known to have excellent electronic counter-countermeasures (ECCM) performance and the potential to realize spectrum sharing in dense electromagnetic…
