- QPSK Matlab Modulation Dual-bit code
Currently, multiple modulation schemes based on QPSK are applied more and more widely. They are involved in digital microwave communication system, digital satellite communication system, broadband access, mobile communication and cable television system. QPSK is quarternary phase-shift keying. It characterizes digital information input through differences of four different phases of carrier. It specifies four phases of carrier. One dual-bit code element is corresponding to two binary information bits. They can be regarded as the synthesis of two 2PSK signals. In QPSK, each modulation can transmit two information bits. They are transferred through four phases of carrier. This design realizes modulation and demodulation of QPSK on Matlab platform. It then verifies relevant theoretical knowledge of QPSK systematically.
