4x4 MIMO vs 2x2 MIMO using space time coding matlab code request

[mohhroub]

HI all ..
i need help to find or any one can show me a matlab code that plot the (4x4 MIMO vs 2x2 MIMO) performances (SNR,BER) using the space time block coding as fast as possible ,please
u can mail me (mohd_yasser2003@yahoo.com)

i dont have anycode on me these days. i used to have em :/.

in case you decide to do it on your own, i suggest you check out "Introduction to Space-Time Wireless Communications" by A. Paulraj.

Im doing it but i need to see other codes to give a hint or idea for the next step in my own code

Numerically, 4-by-4 is equivalent (in terms of BER) to 1-by-8 except that the total power is divided by 4 in the first case, and likewise 2-by-2 is equivalent to 1-by-4 except that the total power is divided by 2. So, if you have the BER of receive diversity with N antennas, then you can do the comparison quickly. However, if you want to do simulation, then you have to program everything as it is explained in theory step by step, which is not so hard, just you need to interpret the theory into MATLAB code.

i need the code for 4x4 MIMO STBC...anyone can help?

here is some code for 2x2 STBC with BPSK
