Closed form expressions for computing the occupied bandwidth of PCM/PSK/PM signals
A computational technique to determine the occupied bandwidth for a class of PCM/PSK/PM signals is presented. The signals considered use either a squarewave or sinewave subcarrier. Closed-form expressions for the occupied bandwidth as a function of the subcarrier frequency-to-bit-rate ratio with modulation index as a parameter are derived using linear-fitting techniques. It is found that the occupied bandwidth for squarewave subcarrier at low modulation index is about 10 to 15 times larger than the sinewave.<>
