Slowing the time-fluctuating MIMO channel by beam forming.

Slowing the time-fluctuating MIMO channel by beam forming.

It has been reported that the number of transmitters that can be used beneficially in a multiple-input multiple-output (MIMO) system is limited by the coherence time of the channel due to difficulties with channel estimation at the receiver. Furthermore, rapid channel fluctuations degrade the perfor...
