Abstract
High mobility and high data speeds are now highly important requirements. The orthogonal frequency division multiplexing (OFDM) structure, which suffers from inter-carrier interference (ICI) in time-varying channels, is the basic core method in digital video broadcasting (DVB). Hence, the bit error rate (BER) is declined. In this paper, the time mirroring (TM) based on the symbol time compression (STC) technique for entire ICI suppression for DVB systems is proposed. In addition, some missing analysis for STC technique and ICI power analysis is introduced. Finally, the computational complexity of the proposed TM scheme is determined. The simulation results show that the proposed scheme reduces the ICI power by a significant amount when compared to the other traditional schemes. In comparison to traditional systems, the BER performance is greatly enhanced, and the eye diagram is entirely opened. In addition, as compared to traditional schemes, the proposed approach can handle normalized Doppler frequency by up to 40% and it has about the same computational complexity as the STC scheme but it is more efficient in terms of computational complexity than the traditional OFDM system.
