Abstract
An Inter-Symbol Interference (ISI) removing method for a received signal executed by a receiver in an Orthogonal frequency division multiplexing (OFDM) system to estimate a frequency-domain data signal carried on the received signal is provided. The method comprises the steps of: removing the first interference of known signal of the received signal; estimating a first data signal according to the received signal; performing a hard decision operation on the first data signal to generate a first frequency-domain signal; performing an Inverse Fast Fourier Transform operation on the first frequency-domain signal to generate a first time-domain signal; creating a tailing signal according to the first time-domain signal; removing a preamble signal from the received signal to generate a second signal; combining the first time-domain signal and the second signal to estimate the frequency-domain data signal.
