A Family of Square-Root Nyquist Filter With Low Group Delay and High Stopband Attenuation

A simple method for square-root Nyquist filter design with low group delay and high and fast decaying stopband attenuation is presented. The method is based on a frequency domain design procedure and can address various roll-off factors. The computation procedure is presented and justified analytica...

Zusammenfassung:A simple method for square-root Nyquist filter design with low group delay and high and fast decaying stopband attenuation is presented. The method is based on a frequency domain design procedure and can address various roll-off factors. The computation procedure is presented and justified analytically. Numerical results show that for a given group delay, the stopband attenuation performance of this proposed technique outperforms the most relevant existing techniques.
