Abstract :
This letter describes the correction of the existing Spectral Correlation Function (SCF) expression of orthogonal frequency division multiplexing (OFDM) signals. The influence of modulated sequences to the cyclostationarity of SCF is introduced, which means the cyclic frequencies of SCF are related to both the symbol period and the modulated sequences period. Theoretical analysis is also validated by simulation results.
