Abstract :
The present-day stage of wireless digital communications development is characterised by the use of spread-spectrum technologies, i.e. direct- sequence spread-spectrum technologies (for example, in systems "of type of IMT- DS/WCDMA/UMTS as well as IMT- MC/cdma2000) by means of a pseudo-random sequence (PRS) and a multiple subcarrier technology (for example, FlashOFDM) using Fast Fourier Transform.
