WebJan 15, 2024 · The roll-off factor has an important effect on the FMT performance. It determines the width of the transmission band at a given symbol rate. The effect of the … WebRoll-off factor, or excess-bandwidth factor (over Nyquist bw B 0): Cut-off frequency: 8 f1 and αcan be adjusted to control the trade-off between the bandwidth and length of the impulse response. α> 0: more bandwidth than Nyquist, but filter is shorter. Bandwidth: Example: Raised Cosine Spectrum
Webwhere the parameter roll-off factor 0 is a real number in the interval 1 that determines the bandwidth of the the spectrum. Since the spectrum is zero for j f > 1+ 2 T s, the bandwidth of the baseband pulse is 1+ 2 T s. For bandpass QAM modulation, the bandwidth is twice that: BW = 1+ T s =(1 +) R s (2) where R s is the transmitted symbol rate.
