  • The future OFDM systems are expected to operate at high transmit frequencies, at high capacities, at high levels of mobility, and the traditional one-tap equalizer is not applicable any more. In this paper, a novel frequency-domain Turbo equalization (FTE) technique for OFDM systems over doubly-selective channels is presented based on the analysis of the ICI generation mechanism. Simulation results indicate the presented approach has significant BER performance and complexity advantages, can mitigate ICI effectively over doubly-selective channels.
