QPSK modulation partial Quadrature Phase Shift Keying, Quadrature Phase Shift Keying means, is a digital modulation. Digital signal quadrature phase shift keying modulation and demodulation technology for its flexibility and versatility which has been widely used, in line with the future direction of development of digital communication technologies. With the development of mobile communication technology, previously used in digital communication systems FSK, ASK, PSK modulation, etc., many excellent modulation gradually being replaced by technology.
