基于调制宽带转换器的重构算法研究

Research on the Signal Reconstruction Algorithm Based on the Modulated Wideband Converter

本文针对OMP算法需要已知稀疏度的缺陷，提出了一种全盲的基于调制宽带转换器的SAMP算法，并利用此算法进行仿真分析，然后与OMP算法进行比较，分析这两种算法的性能，得出SAMP算法在未知目标信号的稀疏度的情况下能和OMP算法一样实现目标信号的频谱重构。

In this paper, a totally blind SAMP algorithm based on modulation wideband converter was proposed in this paper, which required the known sparsity of the OMP algorithm. This algorithm was simulated and analyzed by this algorithm. Then compared with the OMP algorithm, the performance of the two algorithms was analyzed. It was concluded that the SAMP algorithm could be calculated with OMP in the case of the sparsity of the unknown target signal. The same method was used to realize the spectral reconstruction of the target signal.
