QPSK信号的盲解调，假定接收端已经实现载波同步，位同步-Blind demodulation of QPSK signals, assuming the receiver has achieved synchronization, bit synchronization

在qpsk调制过程中实现了接受端的各种同步-Qpsk modulation process in the receiving end is implemented in a variety of synchronization

使用matlab对无线通信中重要的调制技术QPSK进行了仿真设计，包括调制，信道环境模拟，解调，最重要的是解决了无线通信中的载波同步问题，对频偏和相偏进行了估计，也实现了码元同步。-Use matlab important wireless communication QPSK modulation technique simulation design, including modulation, channel environment simulation, demodulation, th
