Wideband code division multiple access signal is non-periodic signal, which always floods in the background noise, bringing difficulties to the signal's reconnaissance. In order to detecting this signal, the detection method based on the quadratic fourth-order moment chip of WCDMA is proposed, and the amount of calculation is reduced by using fast calculation method about fourth-order moment chip...
DS-CDMA in the modern civil and military communications is widely used. Due to its low power spectral density, the DS-CDMA signal always floods in the background noise, bringing difficulties to the signalpsilas reconnaissance. Therefore, DS-CDMA signal detection has attracted attention of researchers. Because the fourth-order moment chip is blind to the arbitrary Gaussian noise, the detection method...
