Blind and semi-blind channel identification methods using second order statistics for OFDM systems

  title={Blind and semi-blind channel identification methods using second order statistics for OFDM systems},
  author={Bertrand Muquet and Marc de Courville},
In this paper two new blind channel identification methods suited to multicarrier system (OFDM) exploiting the redundancy introduced by the adjunction of a cyclic prefix at the emitter and relying on the evaluation of the received signal autocorrelation matrix are presented. The proposed algorithms are able to identify any channel without any constraint on their zeroes location (including non-minimum phase channels) and are robust to the addition of white noise. Moreover a further enhancement… CONTINUE READING
