Abstract：As a compressivesensingbased receiver platform, random demodulator can sample and reconstruct multi/wide bands signals meeting the requirement of sparse spectrum with low sampling rate. This research simplifies this reconstruction algorithm utilizing the priori spectrum information. We propose a novel reconstruction algorithm: inverse matrix, which not only simplifies the calculation but also enhances the performance of signal reconstruction.
