摘要
提出通过Chip延迟相乘与相关矩分析的方法实现对直扩信号扩频序列的估计,理论分析与计算机仿真显示该方法不但能实现对直扩信号扩频序列的估计,而且能提供序列的同步信息,并能适应对直扩信号检测的低信噪比要求.
The paper proposes to estimate the spread spectrum sequence of the direct sequence spread spectral （DSSS） signals by chip-delay-multiply and correlation matrix Analysis. Theory analysis and computer simulations show that it can not only achieve the estimation of the spread spectral sequence, but also can give the synchronization information. The proposed method can fit in with the need of the low signal to noise ratio in the detection of the direct sequence spread spectral signals.
