The application of improved Hadamard measurement matrix in compressed sensing

摘要

Measurement matrix design plays a very important role in the whole process of compressed sensing, for it determines the possibility of the signal compression and the receiver accuracy of the original signal reconstruction. This paper proposes an improved method to construct Hadamard measurement matrix after adequate study of compressed sensing. Simulation and verification is carried out and compared with the Hadamard measurement matrix before improved. The experimental results highly bear out that the proposed matrix has a better measure effect.
