Frequency of Occurrence and Information Entropy of American Sign Language
Andrew Chong, Lalitha Sankar, H. Vincent Poor
American Sign Language (ASL) uses a series of hand based gestures as a replacement for words to allow the deaf to communicate. Previous work has shown that although it takes longer…
Robust Fitting of Ellipses and Spheroids
Jieqi Yu, Sanjeev R. Kulkarni, H. Vincent Poor
Ellipse and ellipsoid fitting has been extensively researched and widely applied. Although traditional fitting methods provide accurate estimation of ellipse parameters in the low-…
A Gibbs Sampling Based MAP Detection Algorithm for OFDM Over Rapidly Varying Mobile Radio Channels
Erdal Panayirci, Hakan Dogan, H. Vincent Poor
In orthogonal frequency-division multiplexing (OFDM) systems operating over rapidly time-varying channels, the orthogonality between subcarriers is destroyed leading to inter-carri…
Distortion Exponent in MIMO Channels with Feedback
Deniz Gunduz, Andrea Goldsmith, H. Vincent Poor
The transmission of a Gaussian source over a block-fading multiple antenna channel in the presence of a feedback link is considered. The feedback link is assumed to be an error and…
K-User Fading Interference Channels: The Ergodic Very Strong Case
Lalitha Sankar, Jan Vondrak, H. Vincent Poor
Sufficient conditions required to achieve the interference-free capacity region of ergodic fading K-user interference channels (IFCs) are obtained. In particular, this capacity reg…
Outlier Elimination for Robust Ellipse and Ellipsoid Fitting
Jieqi Yu, Haipeng Zheng, Sanjeev R. Kulkarni +1
In this paper, an outlier elimination algorithm for ellipse/ellipsoid fitting is proposed. This two-stage algorithm employs a proximity-based outlier detection algorithm (using the…
