摘要
Abstract
For the detection of phase-code signal with low SNR ( Signal-to-Noise Ratio) , two phase-code signal was studied based on double-scale wavelet transform, according to the combination of rough orientation and accurate orientation. The modular maximum of big scale is used to find the range of the singularity, the exact point of the singularity is found on a small scale, so that the detection of two phase-code signal would be achieved. Through the computer emulation, this algorithm can realize the detection of the two phase-code signal accurately when the SNR exceeds 0 dB, detection probability would be upon 95% when the SNR exceeds 3 dB.关键词
