【Abstract】 According to the principle of Hadamard transform, the coding templet size and code symbol number were computed, the creation of Sn circular matrix was introduced particularly. The DMA was chosen to serve as coding templet. The experimental result indicates that Hadamard transform is applied in spectral measurement, and the SNR can be improved effectively when the measurement times are not increased.更多还原
