Research on enhancement of medium wave radio broadcasting signal under adaptive filtering
The paper uses a radio receiver to collect medium wave radio broadcast signals,removing interference factors and performing radio broadcast signal splitting,using adaptive filtering methods to calculate the filter parameters of the broadcast signal,determining the characteristics of the broadcast signal and calculating feature weight values,and combining the calculation results of the number of broadcast signal streams to achieve medium wave radio broadcast signal enhancement.The experimental results show that the design method has a high signal-to-noise ratio and good signal enhancement effect.
