| Abstract(in English) | A new method is proposed for deigning FIR Nyquist filters with zero intersymbol interference and low group delay. It is shown that FIR Nyquist filters that satisfy the time-domain condition of zero intersymbol interference have a property on frequency response where both the magnitude and phase responses in passband are dependent on the stopband response. Then, the design problem become approximation of the magnitude response in stopband only. The proposed procedure is based on the formulation of a linear problem by using multiple Remez exchange algorithm in stopband directly. Therefore, the filter coefficients can be computed by solving the linear equations, and the optimal solution with an equiripple stopband response is easily obtained after applying an iteration procedure. Although the proposed Nyquist filters have an approximate linear phase response only, its group delay can be designed lower than the conventional FIR Nyquist filters with an exact linear phase. |
