differential space time coding

[fab49]

Hello
I have done some simulation on Differential Space time Block Codes but I have a problem with the matlab code. Indeed, my first simulation was done by realizing differential modulation in cascade with STBC at the transmitter and receiver. The obtained result is such the one obtained by Tarokh in "a differential detection scheme for transmit diversity" for BPSK but the method used as the receiver is not same as mine is having first a STBC decoder and then a differential demodulator.
Does anyone can provide me some code that are achieving the same performances as Tarokh using the same methodology?
thank you

I am surprised that no one as any idea about differential. I just need some lines of codes or some explanations that can make me progress in my simulations.
Thanks a lot

Dear fab49; please if you could send me the code for BPSK, i need it
