Four-phase phase shift keying, 16qam modulation, one symbol represents 2 bits; The four phases are "00", "0 1", "10" and "1"respectively; QPSK modulation is adopted to ensure the efficiency and error performance of signal transmission. The implementation of general QPSK also shows the implementation of high-order PSK. The constellation diagram is as follows:
Application of QPSK;
QPSK digital TV modulator adopts advanced digital signal processing technology, which fully conforms to DVB-S standard, and the receiver can be directly received by digital satellite receiver. It can not only achieve high spectrum utilization, strong anti-interference and high cost performance, but also be well compatible with analog FM microwave equipment.
