Zusammenfassung:	This paper presented a semi-blind channel estimation algorithm based on wavelet de-noising in OFDM system. This method adopted wavelet transform in de-noising of auto-correlation matrix estimated value of receiving signal in semi-blind algorithm, so as to eliminate or decrease the influence of channel estimation error caused by noise, and increase channel estimation accuracy. Simulation proved the validity of this method.
