摘要
Abstract
Compressed sensing theory which is proposed recently for sparse signal is a new theory used in signal processing area . It's main innovation is to sample and compress signal at the same time . Measurement matrix is one significant step to imple-ment the innovation , and it's property has a direct effect on the result of signal reconstruction . This essay proposed a new simple method to construct the measurement matrix , utilizing the orthogonality of diagonal matrix with its determinant of non-zero value , and linear representation theory of orthogonal basis . Simulation result proves that the new matrix has a good performance .关键词
