Abstract本发明涉及一种微弱信号的快速提取方法及装置,该装置具有:模数转换器,对混和强噪声的原始目标信号进行采样;主控逻辑器件,接收模数转换器的采样信号,利用从大目标信号中提取的原始特征向量或经过循环更新的特征向量对采样信号进行快速提取计算得到离散化的目标信号;数模转换器,将主控逻辑器件输出的最后提取的离散化的目标信号转换成模拟信号输出;该方法包括以下步骤:对混和强噪声的原始目标信号进行采样;对上述采样信号和特征向量进行快速提取,得到去除强噪声的离散化的目标信号;对上述离散化的目标信号进行数模转换,输出最终目标信号。本发明具有提取快速、实时性强的特点。
Other AbstractThe invention relates to a method and device for rapidly extracting a feeble signal. The device comprises an analog-to-digital converter for performing sampling to an original target signal of the mixed strong noise, a main control logic device used for receiving the sampled signal of the analog-to-digital converter and used for performing rapid extracting to the sampled signal by using the original characteristic vector extracted from a big target signal or through the circularly updated characteristic vector to obtain a discrete target signal by calculation, and a digital-to-analog converter for converting the finally extracted discrete target signal output by the main control logic device into an analog signal output. The method comprises the following steps: sampling the original target signal of the mixed strong noise rapidly extracting the sampled signal and the characteristic vector to obtain the discrete target signal of which the strong noise is removed and performing digital-to-analog conversion to the discrete target signal so as to output the ultimate target signal. The invention has the advantages of rapid extraction and high real-time.
