Thank u, it helps a lot. By the way, could u please recommend me some paper or articles that talk about the scaling factor problem for Alamouti's code in higher order modulation?
I am studing on Alamouti's paper and I can get the same simulation result when using BPSK but not for QPSK, ur code inspires me alot and I want to learn more about scaling factor u mentioned.
Thanks again.

Very good! Clear codes and explanation.
Only one question, why we need these lines:
yHat = sum(hEq.*yMod,1)./hEqPower;
yHat(2:2:end) = conj(yHat(2:2:end));
I mean, if the decision rule is: ipHat = real(yHat)>0;
Then
yHat = sum(hEq.*yMod,1)
will be enough for everything.
Why do we need to divide it by the power of the channel and do the conjugate for
h2*y1 -h1y2* ?
I am a little bit confused here.
Hi Mate
This is really good work just I have simple question in my mind, can i emplement your code to work on IEEE802.16 transmitter receiver?
Thanks in advance
