Single carrier receiver having improved equalizing quality for equilizer and its equalizing method

An equalizer of a single carrier receiver and method thereof include a pre-ghost detection unit, a delay unit, an FF unit, and an FB unit. The pre-ghost detection unit detects one ghost from ghosts having levels higher than a predetermined threshold and detects a time delay of the detected ghost with respect to a main ghost. The delay unit delays an input field synchronization signal for the time delay and outputs a delay signal indicative thereof. The FF unit receives a pre-ghost to filter ghosts received before the detected ghost. The FB unit receives the delayed field synchronization signal to filter the ghosts received after the detected ghost.
