摘要：Adoptive filter techniques are used for noise cancellation in speech signal. The voice carrying DSSSsignal are normally corrupted by noise and the voice signal and noise signal are found to time variant. In such a citationadaptive filtering becomes very relevant. A blocked Adoptive LMS (BLMS) algorithm has been developed in thispaper for the cancellation of noise in Direct Spread Spectrum System (DSSS). The application of BLMS algorithmsbased on adoptive filters in fractional domain on DSSS voice signal indicate an significant improvement in the noisesuppression by 0.46 dB. The BLMS algorithms developed is found to be efficient and simple to adopt for applications.
