In multiple-input multiple-output (MIMO) systems, because signals from different transmission antennas overlap each other at each receiving antenna, channel estimation is no longer feasible, owing to computational complexity when the fading is fast or the number of transmission antennas is large.

In multiple-input multiple-output (MIMO) systems, because signals from different transmission antennas overlap each other at each receiving antenna, channel estimation is no longer feasible, owing to computational complexity when the fading is fast or the number of transmission antennas is large.
