The main aim of this paper is to show on the conceptual level the practical and commercial benefits of signal construction and processing technology based on orthogonal frequency and time domains multiplexing (OFTDM). This technology utilizes mathematical framework of special orthogonal bases with the best time frequency localization. Higher spectral and energy efficiency of telecommunication systems together with robustness against complex realistic channel conditions are achieved. In particular, the level of interference between subcarrier channels in time and in frequency domain is minimized. This approach can have wide implementation in wideband mobile networks (WiMAX, LTE), digital television (DVB-T/H) and other telecommunication systems.
