Multiple Parameter Estimation With Quantized Channel Output

open access: yes, 2010
We present a general problem formulation for optimal parameter estimation based on quantized observations, with application to antenna array communication and processing (channel estimation, time-of-arrival (TOA) and direction-of-arrival (DOA) estimation)

Source bearing and steering-vector estimation using partially calibrated arrays [PDF]

open access: yes, 2009
The problem of source direction-of-arrival (DOA) estimation using a sensor array is addressed, where some of the sensors are perfectly calibrated, while others are uncalibrated. An algorithm is proposed for estimating the source directions in addition to

Performance Improvement for Wideband DOA estimation with White Noise Reduction Based on Uniform Linear Arrays [PDF]

open access: yes, 2016
A method is proposed for reducing the effect of white noise in wide- band uniform linear arrays via a combination of a judiciously de- signed transformation followed by highpass filters. The reduced noise level leads to a higher signal to noise ratio for

Cramer-Rao Bounds for Joint RSS/DoA-Based Primary-User Localization in Cognitive Radio Networks [PDF]

open access: yes, 2012
Knowledge about the location of licensed primary-users (PU) could enable several key features in cognitive radio (CR) networks including improved spatio-temporal sensing, intelligent location-aware routing, as well as aiding spectrum policy enforcement ...

Spatial time-frequency distribution of cross term-based direction-of-arrival estimation for weak non-stationary signal

open access: yesEURASIP Journal on Wireless Communications and Networking, 2019
In the radar array signal processing direction of arrival (DOA), the estimation of weak non-stationary signal is an important and difficult problem when both strong and weak signals are coexisting particularly because the weak non-stationary signals are ...
