1在数字信号的调制方式中QPSK是最常用的一种卫星数字信号调制方式,它具有较高的频谱利用率、较强的抗干扰性、在电路上实现也较为简单。 2主要包括QPSK的调制解调(1, in the way of digital signal modulation, QPSK is the most commonly used method of satellite digital signal modulation. It has high spectrum utilization, strong anti-interference and simple implementation on the circuit. 2 mainly includes modulation and demodulation of QPSK)
