| Research Abstract |
Nowadays, block-wise signal processing with FFT (Fast Fourier Transform) is widely used in wireless communication systems. But, block-wise signal processing degrades seriously in fast time varying channels. This research program proposes a novel scheme that mitigates the performance degradation in such channels. It is shown by computer simulation that the proposed scheme achieves superior performance in fast time varying channels with 0.25 of the maximum Doppler frequency normalized by block size, f_DT.
