Did you have Matlab 7.5 version, there are also some default examples for modulation techniques and even IEEE 802.16 d 2004 WiMAX simulink is exist. (go->help->just type qam or qpsk..)

Enjoy!

mat lab code for qam

Hi freind,
you can not convert between them as i know but you can demodulate at 64 and then modulate at 16.

coding of qam in matlab

Hi Aya,

Do you have Spatial multiplexing matlab code and Space time block coding matlab code? I really need it. I could find some STBC code on google but it's not complete, not working. Please provide me if you have.

Also do you know anything about precoding?
