Abstract :
We propose a novel blind channel estimation method for OFDM systems, the proposed method is based on the relation between amplitude and phase of analytic signal, and estimate the phase-frequency response basing on the estimation of amplitude-frequency response. In particular, the proposed method achieves accurate channel estimation and fast convergence.
