Blind Crosstalk Cancellation for DMT Systems
(20020901)As the deployment of broadband communication systems such as DSL continues to grow, system performance in terms of capacity and error rates is severely limited by crosstalk interference. In order to continue deploying high ... 
Blind Quadratic and Time Frequency Based Detectors from Training Data
(19950120)Timefrequency based methods, particularly quadratic (Cohen'sclass) representations, are often considered for detection in applications ranging from sonar to machine monitoring. We propose a method of obtaining nearoptimal ... 
Broadcast Detection Structures with Applications to Sensor Networks
(20060301)Data broadcasting is potentially an effective and efficient way to share information in wireless sensor networks. Broadcasts offer energy savings over multiple, directed transmissions, and they provide a vehicle to exploit ... 
A Canonical Covariance Based Method for Generalized Joint Signal Representations
(19960420)Generalized joint signal representations extend the scope of joint timefrequency representations to a richer class of nonstationary signals. Cohen's marginalbased generalized approach is canonical from a distributional ...
