  • Based on cyclostationarity of digital modulated signals, many blind signal processing applications can be completed. But the cyclic spectrum structure of signals must be known in premise. Based on Linear Periodically Time-Variant transformation (LPTV) model and aperiodic homogeneous Markov chain model, the Spectral Correlation Density (SCD) expression of OFDM signals is derived. The magnitudes of cyclic spectrum are graphed as the heights of surfaces above a bifrequency plane. Computer simulation results confirm theoretical analysis.
