How to generate QPSK?

The QPSK signal is generated by phase-shifting the carrier. This applies for any carrier frequency. All symbol transitions are possible. I/Q Signals of quadrature modulation.

How QPSK modulation is done?

Quadrature Phase Shift Keying (QPSK) is a form of Phase Shift Keying in which two bits are modulated at once, selecting one of four possible carrier phase shifts (0, 90, 180, or 270 degrees). QPSK allows the signal to carry twice as much information as ordinary PSK using the same bandwidth.

What is modulation Python?

The modulate() function is an inbuilt function in the Python Wand ImageMagick library which is used to changes the brightness, saturation and hue of the image.

Is 4 QAM the same as QPSK?

Yes, QPSK and 4-QAM are effectively the same. Higher order PSK and QAM would be different, but they reduce to the same thing if you only have 4 constellation points. For more information about digital modulation, see Digital Modulation.
