Abstract: PURPOSE: A fast recursive least square-decision feedback equalizer interworking with a least mean square-decision feedback equalizer is provided to realize a channel equalizer interworking a restarting fast recursive least square-decision feedback equalizer with a least mean square-decision feedback equalizer. CONSTITUTION: An LMS(least mean square) equalizer filter(502) receives and filters external input signals, decided data, and an error calculated value by using updated coefficients and segment synchronization. A restart fast kalman tap coefficient updating unit(501) updates coefficients. A trellis decoder(504) reduces a decision error from signals output from the LMS equalizer filter. An error calculating unit(505) calculates the error value by using each output value of the LMS equalizer filter and segment synchronization.
