Abstract :
This paper characterizes constrained FM, CNFM, determines its properties and investigates its spectral efficiency based on the 99 percent bandwidth criteria. Finally, the spectral efficiency of CNFM is compared against MSK and duobinary FM. It is shown that CNFM is spectrally more efficient than MSK, but, it has the same spectral efficiency as duobinary FM.
