# capacity of multi-antenna channel - channel matrix unknown at receiver

Started by November 18, 2004
```Consider the memoryless, discrete time, matrix channels with additive
Gaussian noise of the form Y = HX + Z, where H is the channel matrix,
X is the original signals, and Y is the received signals.

There is a growing body of literature discussing the capacity of such
channel when H is known at the receiver. However, I didn't find any
paper studying the problem when H is NOT known at the receiver, but
known at the transmitter.

thanks a lot
