to my knowledge, ber performance of MMSE is not characteristized yet.
In general, the average ber calculation involves intergration over snr, but snr for MMSE is not readily available.

the general relaship between snr and E0/N0 is as folow:
E0/N0= snrxW/R, where W the frequency bandwidth of the modulated signal
and R is bit rate,
u can read some details in the book of Sklar "fundamental of digital communication"

what about ber, is it all summation for all ber in each branch, or it is the mean of all branch, or min. (...)

This can be the answer for your question.
This is a matlab code.
create a QAMSER.m file
copy this into the file
open and run it in matlab.
You can change m (the modulation number), so you can calculate SER for any QAM channel with rayleigh fading.
(by the way, it gives back the same (...)

There's a ".four" instruction in HSpice for calculating THD but it's not so accurate specially in SC circuits. So there's a very better solution.

In general if you have a total power P and N ransmit antennas, the power is divided uniformly, i.e.: each antenna transmits with P/N. for the normalization, it is usually done for simplicity of exposition without any loss of generality.
If the power is not uniformly distributed, then you have P1, P2, ..., (...)
