in the simulation of alamouti using bpsk, i compare the performance between 2Tx x 1Rx and 2Tx x 2Rx
of course, at the same BER the second is better in SNR effect then the first
but i query that why the simulation of the second end at 7dB while the first is extended to 10dB?
Do you have enough samples to generate the BER calculation? For the 2TX-2RX simulation at about 7dB SNR the BER is about 10^-4. To simulate this BER you should have at least N = 10/Pb = 10 / (10^-4) = 10^5 samples (trials).
As the BER gets smaller the number of trials required increases. Without enough trials you may not get any errors from the simulation. This is true for any BER simulation.
Is there any one of you have code for alamouti scheme.i am very thankful if you ssend it to me.
I am actually working on SNR estimation.so far i do it for SISO.now i want to extend it to MIMO.so help me out.plz

Mate can u upload or email at
collective.ajay(at)gmail.com for the matlab file for implementing the alamouti paper . i desperately need it for my assignment . thanks in advance

Hi ,
First u go through the IEEE paper by Alamouti .
"A Simple Transmit Diversity Technique for Wireless Communications" IEEE October 1998
It ll give you basic idea of implementing the Alamouti scheme.
