在利用小波变换提取二相编码信号的调制特征时,尺度参数的设置很重要。文中通过正弦波频率估计的综合方法来精确的估计出信号的载频,从而得到合适的尺度参数,并得到小波脊线。通过计算小波脊线上小波变换的模值来得到二相编码信号调制特征。实验结果表明了此方法在较低信噪比下的有效性。
When using the wavelet transform to extract the modulation characteristics of two-phase encoded signals, the setting of the scale parameters is very important. In this paper, the carrier frequency of the signal is estimated accurately by an integrated method of the frequency estimation of the sine wave, so that the appropriate scale parameters are obtained and the wavelet ridge is obtained. The modulation characteristics of two-phase coded signal are obtained by calculating the modulus of wavelet transform on wavelet ridge. Experimental results show the effectiveness of this method at lower SNR.
