| 摘 要： | 总结了在低信噪比下直接序列扩频信号检测和参数估计的方法，并比较各个方法的优缺点。理论分析表明，信号检测、参数估计不仅和信噪比有关，而且依赖于观察时间、带宽、伪码码长、带内干扰等因素。

| Abstract: | This paper summarizes the detection and parameter estimation methods of directsequence spread-spectrum signal in low signal to noise ratio conditions, and compares their advantages and disadvantages. Theory analysis indicates that the signal detection and parameter estimation is not only associated with signal to noise ratio, but also with the observation time, bandwidth,the length of pseudo random code,in-band interference and other factors. |
