The code of QPSK modulation and demodulation technique has been developed according to the theory. The theoretical description of QPSK modulation and demodulation are available in the book of "communication system " by SIMON HAYKIN.

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
The comments are detailed!
Thak you very much
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 email@example.com .
i want mimo equation of qpsk modulator and de modulator
