Effect of Non-Linearity on the Performance of a MIMO Zero-Forcing Receiver with Channel Estimation Errors
— Non-linear amplitude distortion may be the key impairment in some practical multiple-input multipleoutput (MIMO) communications systems. However, there are only a few past inve...

Earth mover distance over high-dimensional spaces
The Earth Mover Distance (EMD) between two equalsize sets of points in Rd is defined to be the minimum cost of a bipartite matching between the two pointsets. It is a natural metr...
