Pulse Shaping & Eye Diagram

Pulse Shape

Parameters

Roll-off α 0.35 Symbol Rate R_s (sym/s) 1 Symbols to show 20

Channel

Timing offset (ε/T) 0.00 SNR (dB) 30

Nyquist ISI Criterion
A pulse p(t) causes zero ISI iff:
p(nT) = { 1, n=0; 0, n≠0 }

Raised Cosine:
α=0: ideal sinc (min BW, max ISI sensitivity)
α=1: widest BW, most robust to timing errors

BW = (1+α)/(2T)
