Abstract : In broadband wireless system, the signal energy is scattered and reflected from objects in the environment, components of the signal arriving at the receiver are spared out over a longer period of time than is desirable. The challenge is then to provide a high performance reliable data link that can operate with the restricted receiver power levels, severe channel fading due to multipath reflections and interfering energy from other devices nearby. The Performance of the Orthogonal Frequency Division Multiplexing (OFDM) is degrade due to Doppler frequency or frequency drift between transmitter and receiver oscillator which causes frequency offset and leads to Inter- Carrier-Interference (ICI). This paper represents, a general reduced-rate orthogonal frequency division multiplexing (OFDM) transmission scheme for inter-sub channel interference (ICI) self-cancellation over high-mobility fading channels.
