Abstract: Disclosed is a channel estimation and equalization method and system. The method inserts a pilot signal in the time domain into a guard interval, uses a hard decision signal in the frequency domain to estimate a frequency response of the channel, and equalizes a radio channel distortion through the estimated channel value.
