Detecting Abrupt Changes in Channel Covariance Matrix for MIMO Communication
Runnan Liu, Liang Liu, Dazhi He +2
The acquisition of the channel covariance matrix is of paramount importance to many strategies in multiple-input-multiple-output (MIMO) communications, such as the minimum mean-squ…
Joint DOA and Frequency Estimation with Sub-Nyquist Sampling for More Sources than Sensors
Liang Liu, Ping Wei
In this letter, we apply previous array receiver architecture which employs time-domain sub-Nyquist sampling techniques to jointly estimate frequency and direction-of-arrival(DOA)…
A Simplified Sub-Nyquist Receiver Architecture for Joint DOA and Frequency Estimation
Liang Liu, Ping Wei
Joint estimation of carrier frequency and direction of arrival (DOA) for multiple signals has been found in many practical applications such as Cognitive Radio (CR). However, Nyqui…
Joint DOA and Frequency Estimation with Sub-Nyquist Sampling
Liang Liu, Ping Wei
In this paper, to jointly estimate the frequency and the direction-of-arrival(DOA) of the narrowband far-field signals, a novel array receiver architecture is presented by the conc…
Off-grid DOA Estimation Based on Analysis of the Convexity of Maximum Likelihood Function
Liang Liu, Ping Wei
Spatial compressive sensing (SCS) has recently been applied to direction-of-arrival (DOA) estimation owing to advantages over conventional ones. However the performance of compress…
