Cpfsk spectral efficiency
WebHow do these plots relate to power efficiency? Minimum Shift Keying (MSK) • MSK is a continuous phase FSK (CPFSK) where the frequency changes occur at the carrier zero crossings. 1.The difference between the frequencies is always 1⁄2 of the data rate. 2.– WebIn addition to its spectral characteristics, CPFSK possesses two other appealing characteristics. First, CPFSK maintains a constant amplitude signal, which is appropriate for nonlinear channels, as it will experience fewer adverse effects than a non-constant envelope signal. Hence, a nonlinear high power amplifier in the signal path is acceptable.
