Abstract :
In OFDM systems, the Wiener filter could be an important key for channel estimation. In some cases, the Wiener filter needs SNR estimation for accuracy. This paper introduced some SNR estimation methods for wiener filter in OFDM system and made a simulation. At last, give a conclusion for the performance.
