# 基于等角紧框架的稀疏信号重构算法Sparse Signal Reconstruction Algorithm Based on ETF

Abstract: As sparse representation of signals has excellent characteristics, it has been applied in several fields of signal processing. However, the computational complexity has become a major obstacle in practical application. Frame theory is a new research direction and can be more flexible repre-sentation signal. In this paper, with the characteristics of sparse signal and frameworks, we propose a sparse signal reconstruction algorithm based on ETF, and then simulate and verify it.
