Abstract:
A high mobility algorithm is introduced for OFDM systems based on the FFT which can compensate Doppler shifts in time-variant channels with low complexity. We first propose a channel matrix inversion algorithm with a complexity similar to FFT and then introduce a channel matrix construction based on matching pursuit algorithm.
