  • Abstract
    This paper proposes a cognitive positioning architecture. This architecture uses cyclostationary analysis to understand the contents of the spectrum surrounding the receiver and exploit this information for activating the necessary tracking and demodulation loops. This paper assumes the presence of CDMA and OFDM signals. The results show the performance of the spectrum sensing technique used along with the expected positioning accuracy.
