摘　　要：采用提取信号相位并用直方图统计的方法对BPSK、QPSK、OQPSK、UQPSK信号进行识别,并分析不同噪声背景下对这四种信号识别的影响。仿真结果表明在满足一定信噪比的条件下,能够完成对这四种调相信号的识别。The methods of signal phase extraction and the histogram statistics are put forward firstly, which are used to identify the Phase Shift Keying（PSK） signals, such as BPSK,QPSK, OQPSK and UQPSK. Then the effects of discriminated four signals are analyzed under different noise environments. The simulation results show that this new method can automatic recognize the Phase Shift Keying（PSK） signals in certain SNR.
