Multicarrier modulation has been adopted in many modern communication systems because of its many appealing

properties. Its relatively high out-of-band radiation has spurred many techniques to shape the power spectral density (PSD)

of multicarrier signals, including spectral precoding and pulse shaping. We derive a general expression for the PSD which is

valid for subcarrier-specific pulses and for spectral precoders operating over multiple blocks. The only statistical assumptions

on the vector-valued sequence modulating the active subcarriers are wide-sense cyclostationarity and properness. The applicability

of the result to a number of popular multicarrier formats is discussed.
