摘要： PURPOSE: A method for forming an FIR(Finite Impulse Response) filter in a phase equalizer is provided to improve the magnitude of a phase equalizer by using system identification and an RLS(Recursive Least Square) adaptive algorithm. CONSTITUTION: An analog IIR(Infinite Impulse Response) filter is formed at a phase equalizer(S101). A coefficient value of the IIR filter is obtained by using a binary transform method and transforming a phase and a magnitude characteristic of the IIR filter(S103). A difference between an output of an unknown part and an output of an adaptive model is obtained by using an RLS adaptive algorithm(S105). A minimum value of the difference between the output of the unknown part and the output of the adaptive model is determined by feeding back the obtained difference to the adaptive model(S107). A coefficient value of an FIR filter is determined if the difference between the output of the unknown part and the output of the adaptive model is the minimum value(s109).

摘要： A method for eliminating aliasing in a sub band adaptive filtering system and the sub band adaptive filtering system without alias are provided to improve the performance of the sub band adaptive filtering system by removing an interband aliasing extracted from each sub band signal by using a bandwidth-increased linear phase FIR analysis filter. An input signal is passed through a plurality of sub-band analysis filters to remove the input signal passed through the unknown system. The passed input signal is classified into a plurality of sub-band signals. The sub-band signal is down-sampled. The down sampled sub band signal is passed through the corresponding sub band adaptive filter. An interband aliasing signal is extracted from the down sampled sub band signal. The interband aliasing signal extracted from the down sampled sub band signal is removed. An aliasing extraction filter extracts the interband aliasing signal from the down sampled sub band signal.
