在分析软件无线电数据采集方法和小波理论的基础上，提出了软件无线电中宽带信号的双通道数据采集方法。在这种方法中，利用小波理论的方法进行数据恢复与补偿，并提出了解决分割滤波器设计中精度不足的方法。
Based on the analysis of software radio data acquisition method and wavelet theory, a dual channel data acquisition method of wideband signal in software radio is proposed. In this method, the data recovery and compensation are carried out by using the wavelet theory, and a method to solve the problem of the accuracy of the segmentation filter is proposed.
