| 摘 要： | 针对直接序列扩频（DSSS）信号检测的问题，提出了一种对接收信号时域自相关进行小波分解的方法。该方法对于进行了载波调制的直扩信号，其所在频带未知时无法设计前置滤渡器，从而造成检测性能下降的情况，给出了一种可行的解决方案。计算机模拟表明，在该情况下，本方法具有较好的检测性能。

| Abstract: | This paper presents a method of Direct Sequence Spread Spectrum(DSSS) signal detection which uses the wavelet to decomposite the autocorrelation of the received signal.As we know,in some conditions,it is impossible to design a prefilter when the frequency band of carrier-modulated DSSS signal is unknown,and this will degrade the detection performance.The presented method gives a feasible solution to this problem and the simulation results show that it can improve the detection performance. |

| Keywords: | DSSS signal results show that it can improve the detection wavelet decomposition |
