Abstract
In the spectrum estimation algorithm based on Compressed Sensing, the selection of measurement matrix has significant influence on whether can estimate the signal power spectrum with high precision. In the article, it briefly describes the basic principles of spectrum estimation algorithm and the common measurement matrixes. In addition, it presents a detailed comparison and analysis of the construction method, pros and cons among random measurement matrix, structured measurement matrix and deterministic measurement matrix. On this basis, aiming at single-tone, multi-tone and QPSK signals, the feasibility of six kinds of measurement matrixes used in power spectrum estimation based on compressed sensing were validated and compared the estimation performance by simulations. The simulation results show that Toeplitz matrix can obtain the minimum NMSE at the same compression ratio.
