Using colored noise to simulate actual environmental background has important application valuable for laboratory semi-physical simulation experiment.based on Wiener best filter theory

a colored noise generation algorithm is proposed and an embedded hardware and software platform is implemented based on Matlab GUI and TMS320F2812 digital signal processor chip.The validation tests show that the system can real-time output 10 kHz bandwidth colored noise signal setting spectral structure

and the error between statistical spectral characteristics of output signal and setting spectral characteristics is less than 3dB

which meets the special requirements of the practical applications of the colored noise

and has broad application prospects.
