Abstract :
A generalised closed form expression for the power spectral density (PSD) of M-ary variable index continuous phase FSK (VI CPFSK) has been derived using the Transform technique. Examples are presented for typical cases with input levels 2, 4 and 8. Approximation results are presented for comparison.
