    Abstract: PURPOSE: An adaptive channel equalizer and method thereof are provided to improve the performance of a channel equalizer by increasing the size of a previously distorted part in a transmission end. CONSTITUTION: A first filter(200) eliminates inter-symbol interference components from a reception signal. A first filter(210) eliminates the inter-symbol interference components from a transmission signal. A filter control unit(220) controls the filter coefficient of the first filter and a second filter. The filter control unit detects estimation errors. A two-way signal includes the transmission signal and the reception signal.

    Abstract: PURPOSE: A tap update control device is provided to improve noise level estimation performance by restricting the number of tap update times using simple structure. CONSTITUTION: A feed forward filter(100) filters inputted signal. The feed forward filter outputs the filtered signal to a first adder(120). A feedback filter filters the signal outputted from a decision unit(130). The feedback filter outputs the filtered signal to the first adder. The first adder adds the inputted signals. The decision unit determines the symbol based on the inputted signals.
