+ 100 Points- Quary in WiMAX model.

Dear all
I am in urgent need to solove the quary in wimax MIMO-OFDM mode.
In this model, after running the program, 1 is to be entered for including the MIMO and O for single input single output system.

How ever my qaury is in both the cases, with same parameter (i.e. channel bandwidth, SNR etc), i am getting the same BER.
Ideally using MIMO-Alamouti configuration, the BER should be reduced.
I want to know how i can achive the lower Bit Error Rate using MIMO configuration in this model only. or which parameter(s) i have to set for comparing the BER performance of MIMO and SISO i.e by entering 0 and 1 in this model.

I have run this model many times and in each configuration i am getting the same bit error rate for MIMO and SISO configuration. i donot know why....

Kindly give me replay as soon as possible.

Hi,

You may use this model; it is wonderful.

Good Luck!

This model is given in MATLAB-2009 help. As a demo model.
I am analyzing the model which is given in MATH work that i have attached..

Use 2 uncorrelated noise sources (set properly random generator) for both chanels.

Please specify the noise sources or Which Random Generator?
Tell which parameter should be changed?
