摘要：
Realized the compressed sensing based on FPGA. The system sparseed the image date by using the 3-level lifting wavelet transform, measured the sparse data by using the hadamard matrix, and reconfigured the data by using the orthogonal matching pursuit. The system realized the compressed sensing based on NIOSII, optimized the hardware structure of stochastic measure matrix. It reduced the usage of resource and kept the speed. The system has the better reconfiguration effect, less distortion and uses less hardware resource. © 2013 IFSA.
