A spectral method for periodic estimation of the PN sequences in lower SNR DS-CDMA signals
Chang Tianqi, Zhengzhong Zhou · 2003
We propose a new method based on the reprocessing of the power spectral density of 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 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.
