一种新的高动态范围混合信号的弱分量获取方法

Study on New Method for Obtaining Weak Component of High Dynamic Range Mixed Signal

为了有效地获取高动态范围混合信号中的微弱分量,提出了一种基于最小均方差的感知矩阵获取方法。这种新的感知矩阵可以在抑制强分量的同时保留微弱分量;该矩阵不仅满足约束等距性条件而且还可以有效地减少噪声干扰。实验结果表明,该方法能有效地实现高动态范围混合信号中微弱分量的获取。

In order to obtain the weak component of the high dynamic range mixed signal effectively, a method of obtaining a minimum mean square error was proposed. The new sensing matrix can preserve .the weak component while inhibiting the strong component, which can not only satisfy the constraint of the constraint, but also reduce the noise interference. Experimental results show that this method can effectively achieve the acquisition of weak components in high dynamic range mixed signal.
