Abstract	One of possible options to achieve good frequency efficiency in mobile communication is the OFDMA method. It provides rather good performance for the point-to-multipoint transmission in systems without considerable Doppler frequency offset. However, increasing of the used frequency band and permanent growing of the traffic make Doppler shift influence more and more critical point in radio modems design. Here a principally new method of multiple access - so called frequency bank signal (FBS) - is proposed. FBS combines the phase shift compensation used in the PAL-TV system, OFDMA principle and spread spectrum idea with Walsh functions. This method allows mitigating influence of multipath propagation and Doppler shift. The main FBS advantage is that the error probability is almost totally non-sensitive to the Doppler effect, separate signals delay and reflected signals influence. FBS signal don't need of special pilot, synchronization or equalization signals
