摘要 |
A method of initializing an equalizer of VSB DTV receiver and an equalizer using the same are provided. The method includes the steps of: obtaining a channel estimation value by estimating an impulse response of a channel from a received signal, initializing a backward filter by using the channel estimation value; generating an imaginary training signal by an arithmetical operation for the channel estimation value and a generated known training sequence; and initializing a forward filter by using the imaginary training signal.
