I played with this quite a bit and improved it for my purpose. It's amazing how well this modulation technique still works even when noise is added to the signal.

Good to see you guy from Bangladesh. You are such a lifesaver.

Thank you very much!
You totally save me from my MATLAB simulation experiment! Such a good guy!


thank you! wihout noise

Thank you very much. I have to use QPSK modulation in OFDM system. After that, I want to introduce some random carrier frequency offsets in various sub carrier frequencies. This offset may be modeled by a Gaussian RV with rms value equal to 1/3 to 1/2 percent of the frequency spacing. Can anybody please help me with that, Please guy's, my email id is .
