Nyquist filters with robust performance against timing jitter

We propose two novel techniques for designing finite impulse response (FIR) Nyquist filters with zero intersymbol interference, good robustness to timing jitter and satisfactory stop-band performance. The first technique is a special kind of windowing method. The second technique is a minimax method resulting in equiripple FIR Nyquist filters which can be optimally partitioned into a matched transmit and receive filter pair. Examples show superior performance of the proposed pulse shapes compared to the existing techniques.
