A Wavefront Array for URV Decomposition Updating
(1995)
The rank revealing URV decomposition is an effective tool in many signal processing applications that require the computation of the noise subspace of a matrix. In this paper, we consider a parallel architecture for updating ...
Blind MIMO FIR Channel Identification Based on Second-Order Statistics with Multiple Signals Recovery
(1996)
To separate and recover multiple signals in data communications, antenna arrays and acoustic sensor arrays, the impulse responses of multiple-input/multiple-output (MIMO) channels have to be identified explicitly or ...
A Super-Resolution Parameter Estimation Algorithm for Multi- Dimensional NMR Spectroscopy
(1995)
In this paper, we will propose a super-resolution scheme for the parameter estimation of multi-dimensional (M-D) NMR spectroscopy. M-D NMR signals can be modeled as the summation of M-D damped sinusoids. The frequencies ...
On the Convergence of Blind Channel Equalization
(1995)
Baud-rate blind equalization algorithms may converge to undesirable stable equilibria due to different reasons. One is the use of FIR filter as an equalizer. It is proved in this paper that this kind of local minima exist ...
Improved Parameter Estimation Schemes for Damped Sinusoidal Signals Based on Low-Rank Hankel Approximation
(1995)
The parameter estimation of damped sinusoidal signals is an important issue in spectral analysis and many applications. The existing algorithms, such as the KT algorithms [8] and the TLS algorithms [13], are based on the ...
A Structured Low Rank Matrix Pencil for Spectral Estimation and System Identification
(1996)
In this paper we propose a new parameter estimation algorithm for damped sinusoidal signals. Parameter estimation for damped sinusoidal signals with additive white noise is a problem of significant interests in many signal ...
Joint Optimal Power Control and Beamforming in Wireless Networks Using Antenna Arrays
(1997)
The interference reduction capability of antenna arrays and the power control algorithms have been considered separately as means to increase the capacity in wireless communication networks. The MVDR (Minimum Variance ...
Adaptive Blind Multi-Channel Equalization for Multiple Signals Separation
(1995)
This paper investigates adaptive blind equalization for multiple- input and multiple-output (MIMO) channels and its application to blind separation of multiple signals received by antenna arrays in communication systems. ...
Two-Dimensional Spatial Smoothing for Multipath Coherent Signal Identification and Separation
(1995)
The existing spatial smoothing (SS) technique, although it is effective in decorrelating coherent signals, is considered applicable only to uniformly spaced linear arrays which are very sensitive to the directions-of-arrival ...
Blind Adaptive Equalization of SIMO Channels Based on Second- Order Statistics
(1996)
This article investigates blind adaptive equalization for single- input/multiple-output (SIMO) channels. A second-order statistics based algorithm (SOSA) and a modified second-order statistics based algorithm (MSOSA) for ...
