The following article comprises three main parts. The first one generally describes two methods of low level signals detection which are in the interest of this study. The signal spectrum averaging technique is shown as well as the method exploiting averaged spectrum of the signal raised to the power of 2n (nN). Additionally, this section briefly presents proposed enhancements and modifications of these two solutions, which allow to exploit them fully as tools for the DS-CDMA low level signals detection. The second part shows a general view of the used equipment and a block diagram of the created laboratory stand. In the last section the study results, showing the detectable DS-CDMA SNR levels and narrowband interference elimination possibilities, are presented.
