Abstract :
In Gaussian white noise environment, the DSSS signal parameters estimation which based on spectral correlation can get better parameter estimation results, but in the colored noise environment, its performance declined. In this paper, we have discussed the estimated effectiveness of this method in colored noise environment and proposed an improved method based on ANFIS network. Through computer simulation, it demonstrated that the improved method is effective.
