초록
The present invention relates to blind decision feedback equalization. The present invention selects one of a filter signal and a quantized signal as an input signal of a feedback filter in the DFE and update the tap coefficient according to the SAG flag f[k] by including a main filtering unit, a SAG flag determining unit and a blind feedback controlling unit. The present invention prevents decrement of a performance caused by an error propagation and also improve a convergence performance in an equalization apparatus and reduce a symbol error rate (SER) at a steady state after converging. In conclusion, the present invention can be used effectively to a receiver in a digital TV, which is required the blind equalizer.
