摘要:
In this paper, We propose a kind of new method based on the reprocessing of the power spectral density of the direct sequence code division multiple access (DS-CDMA) signals, it can solve the difficult problem of periodic detection and estimation of the PN sequence in the DS-CDMA signals. The results of computer simulation show that these methods can work well on the lower signal to noise ratio (SNR) input signals.
