| Abstract(in English) | From the viewpoint of the efficient use of frequency resources in mobile radio service, authors have been investigating the feature detection scheme using the Cyclic Prefix (CP) attached in the OFDM signal, which is generally applied in current mobile communication systems. The detection scheme is firstly to obtain the conjugate product of the OFDM signal and its delayed signal, then take Fourier transformation of such product, which is called Cyclostationary Autocorrelation Function (CAF) addressing the cyclostationarity nature. In this report, the Output S/N at the feature detector output is clarified by an analytical expression. An analytical approach is investigated by modeling the power spectral densities of the OFDM signal and input noise and by executing the mathematical operations on the combinations of OFDM signal and input noise. The Output S/N (Signal to Noise Power Ratio) consists of , (i) significant feature component in the OFDM signal, (ii) noise component caused by the multiplication of two OFDM signals, (iii) noise component caused by multiplication of the OFDM signal and input noise, (iv) noise component caused by multiplication of two input noise. We discuss the influences of the above four component to the Output S/N performance. The simulation results are also indicated for sake of comparison with the analytical results. |
