Abstract

Accurate channel estimation is necessary for coherent detection and adaptive control techniques, e.g., adaptive modulation and channel coding, of multi carrier signals. In this paper, we study frequency(or time)-domain channel estimation with transform and without transform, using frequency (or time)-multiplexed pilot. It is shown that the frequency (or time)-domain channel estimation is equivalent to windowing of the delay time-domain impulse response (or Doppler frequency-domain spectrum) obtained by discrete transform as discrete Fourier transform (DFT).
