Subplot(1,2,1) t=t*Tsym plot(t,p) title('Sinc pulse') Nsym = 80 %filter span in symbol duration L=16 %oversampling rate, each symbol contains L samples Program 2: Sinc pulse and its manifestation in frequency domain Tsym=1 %Symbol duration Matlab code for Program 1 is available is available in the book Wireless Communication Systems in Matlab. Program 1: sincFunction.m: Function for generating sinc pulse This article is part of the book Wireless Communication Systems in Matlab, ISBN: 978-1720114352 available in ebook (PDF) format (click here) and Paperback (hardcopy) format (click here). Thus the sinc pulse satisfies the Nyquist criterion for zero ISI. ![]() From the time-domain plot, the value of the sinc pulse hits zero at integral multiple sampling instants seconds except at where it peaks to the maximum value. Following Matlab codes generate a sinc pulse with and plot the time-domain/frequency-domain response (Figure 1).
