Sparse representation has been demonstrated to be a powerful tool in classification of hyperspectral images (HSIs). The spatial context of an HSI can be exploited by first defining a local region for each test pixel and then jointly representing pixels within each region by a set of common training atoms (samples). However, the selection of the optimal region scale (size) for different HSIs with different...
Coordinated Multi-point Joint transmission with ideal channel state information can yield significant performance improvement due to coordinate inter-cell inferences, however the performance gains would be distinctly impacted with imperfect channel state information. In this paper, we show how downlink CoMP JT can be supported by an enhanced feedback method with reasonable feedback overhead. The feedback...
