| 摘 要： | 构造了一种新的小波基函数，提出了一种基于连续小波变换（CWT）的检测方法，并以叠加高斯白噪声的二相编码信号为例进行了算法仿真。仿真结果表明，这种方法对较低信噪比下二相编码信号的检测效果良好，在信噪比为-6．7dB时仍然能够准确地识别出二相编码信号。

| Abstract: | In this paper,a new wavelet basis function is constructed,and a new method of detecting two-phase code signal based on continuous wavelet transform(CWT) is provided,and the simulation test of two-phase code signal mixed with Gauss white noise has been performed.The simulation results show that this method has good detection effect of two-phase code signal under the conditions of low SNR and can detect a two-phase code signal accurately when the SNR is-6.7 dB. |

| Keywords: | two-phase code signal continuous wavelet transform white noise |
