Channel state information based LLR clipping in list MIMO detection
—Suboptimal detection schemes, such as list MIMO detection, often face the challenge of having to “guess” at the decision reliability for some of the detected bits. A simple ...

Simultaneous surveillance camera calibration and foot-head homology estimation from human detections
We propose a novel method for automatic camera calibration and foot-head homology estimation by observing persons standing at several positions in the camera field of view. We de...

Complex Activity Representation and Recognition by Extended Stochastic Grammar
Stochastic grammar has been used in many video analysis and event recognition applications as an efficient model to represent large-scale video activity. However, in previous works...

Application of smoothed estimators in spectrum sensing technique based on model selection
In cognitive radio networks, secondary user (SU) does not have rights to transmit when the primary user (PU) band is occupied, that's why a sensing technique must be done. Rec...

High-Diversity Cooperative Spectrum Sensing in Cognitive Radio Networks
This paper develops a cooperative scheme among cognitive radios (CRs) to increase the spectrum sensing performance. CRs adaptively transmit local binary decisions to a fusion cente...
