摘　　要：提出了一种低信噪比下正交相移键控(QPSK)信号盲识别和盲解调的方案,能够用于0dB情况下的QPSK信号盲识别和盲解调。仿真表明该方案具有实用性和可行性。This paper brings forward a project ternary phase shift keying （QPSK） signal in recognition and blind demodulation of QPSK the project has practicability and feasibility. of blind recognition and blind demodulation of quar- low signal to noise rate, which can be used for blind signal in the state of 0 dB. The simulation shows that
