Good Day to all

Dear friends ,
I'm asking if there is a relation to calculate the channel H.
However as I think in most of STBC , they assume that the receiver has perfect channel state information (CSI).
But one Dr. asked me to calculate it exactly ....so i'm little supprized because Alamouti in his famous paper didn't do that.

So please any help or notes regarding with this matter I'll be thankful.

Regards
 

What do you mean by calculating H?
 

Thank you for interest ...

The channel coefficient H is the path gain from transmit antennas Tx to receive antennas Rx

So I don't know how may calculate it as a fixed value ?? or what the relation to calculate it.
This H , it is h in Alamouti Paper"A Simple Transmit Diversity Technique
for Wireless Communications"

where h= α.exp(jθ)

Any notes please...

Regards to all..
