AbstractBandwidth efﬁcient linear modulations require a pulse shape with ﬁnite support in the time domain while simultaneously achieving good spectral containment in the frequency domain. The square-root Nyquist pulse achieves zero intersymbol interference (ISI) at its matched-ﬁlter output but does so with inﬁnite support in the time domain. This paper investigates three different methods for generating an FIR approximation of a square-root Nyquist pulse.
