Abstract
Measurement matrix design is a very significant part in the whole process of compressive sensing, the ratio of the signal compression and the receiver reconstruction accuracy of the original signal are all determined by it. An improved Hadamard measurement matrix based on Walsh code for compressive sensing is proposed in this paper. Simulation results demonstrate that the measure performance of the proposed measurement matrix is better than original Hadamard measurement matrix.
