Considering the importance of the high performance of white noise in signal processing, a novel method of generating white noise with high performance is proposed. Firstly, the model of the pseudo random sequence is identified. Secondly, the pseudo random sequence is dealt with by smoothing, real-time identification and repeated whitening. Finally, the higher performance of white noise is obtained. Simulation results show that the white noise produced by this method has higher performance.
