Abstract :
Cyclostationarity is an important characteristic of signals. The orthogonal frequency-division multiplexing (OFDM) signal is cyclostationary. Explicit formulas for the spectral correlation density (SCD) for OFDM signal are derived. To illustrate the spectral correlation characteristics of OFDM signal, the magnitudes of the spectral correlation functions are graphed in graphical terms as the heights of surfaces above a bi-frequency plane. The accurate analytic expression of the SCD function is very helpful for blind signal processing.
