摘要
微弱信号的提取在信号检测中占据十分重要的地位,文中研究了一种基于TS201芯片的微弱信号的检测平台设计,利用正弦信号的特性,进行多重自相关运算,有效的提高信噪比,提取淹没于噪声背景下的微弱信号。文中给出了具体的硬件结构设计和算法实验。实验结果表明,检测平台能有效的提取微弱信号。
Weak signals extraction plays an important role in signal detection. This paper studies a design of weak signal detection platform based on TS201 chip. It conducts multi-Layer auto correlation calculations by making use of the characteristics of sinusoidal signal, which effectively improve signal to noise ratio so as to extract the weak signals submerged in the background of noise. Specific hardware structure design and algorithm experiment is mentioned in this paper. The experiment results show that the detection platform can effectively extract weak signals.
