Permutation Enhanced Parallel Reconstruction with A Linear Compressive Sampling Device
Hao Fang, Sergiy A. Vorobyov, Hai Jiang
In this letter, a permutation enhanced parallel reconstruction architecture for compressive sampling is proposed. In this architecture, a measurement matrix is constructed from a b…
Finite-Length and Asymptotic Analysis of Correlogram for Undersampled Data
Mahdi Shaghaghi, Sergiy A. Vorobyov
This paper studies a spectrum estimation method for the case that the samples are obtained at a rate lower than the Nyquist rate. The method is referred to as the correlogram for u…
Permutation Meets Parallel Compressed Sensing: How to Relax Restricted Isometry Property for 2D Sparse Signals
Hao Fang, Sergiy A. Vorobyov, Hai Jiang +1
Traditional compressed sensing considers sampling a 1D signal. For a multidimensional signal, if reshaped into a vector, the required size of the sensing matrix becomes dramaticall…
Efficient Transmit Beamspace Design for Search-free Based DOA Estimation in MIMO Radar
Arash Khabbazibasmenj, Aboulnasr Hassanien, Sergiy A. Vorobyov +1
In this paper, we address the problem of transmit beamspace design for multiple-input multiple-output (MIMO) radar with colocated antennas in application to direction-of-arrival (D…
Sum-Rate Maximization with Minimum Power Consumption for MIMO DF Two-Way Relaying: Part I - Relay Optimization
Jie Gao, Sergiy A. Vorobyov, Hai Jiang +2
The problem of power allocation is studied for a multiple-input multiple-output (MIMO) decode-and-forward (DF) two-way relaying system consisting of two source nodes and one relay.…
