IQ Space Frequency Time Codes for MIMO-OFDM Systems
Abstract: In this paper, we study concatenated coding for MIMOOFDM systems. The proposed concatenated system achieves full spatial and frequency diversity at much lower complexity ...

A universal scheme for Wyner-Ziv coding of discrete sources
We consider the Wyner-Ziv (WZ) problem of lossy compression where the decompressor observes a noisy version of the source, whose statistics are unknown. A new family of WZ coding a...

Kernel Sparse Representation for Image Classification and Face Recognition
Recent research has shown the effectiveness of using sparse coding(Sc) to solve many computer vision problems. Motivated by the fact that kernel trick can capture the nonlinear sim...
