In this paper we introduce a blind parameter identification algorithm for Orthogonal Frequency Division Multiplexing (OFDM) signals.
Radio Monitoring Systems that detect illegal signals transmitted by unlicensed devices. Index Terms- Blind processes, Parameter identifications,. OFDM systems, ...
It is necessary to identify the existence and estimate the key parameters OFDM systems in cognitive radio contexts. In this paper, we propose a scheme to ...
Blind modulation recognition techniques have been proposed to discriminate between single-carrier and multi- carrier modulations and to estimate their ...

Blind modulation classification (MC) determines the modulation type of the received signal, ensuring proper demodulation and retrieval of the transmitted data [ ...
In the context of cognitive radio or military applications, it is a crucial task to distinguish blindly various OFDM based systems (e.g., Wifi, Wimax, ...
Oct 22, 2024 · Therefore we propose four new algorithms to estimate the parameters of OFDM modulated signal (especially the subcarrier spacing) relying on (i) ...
Moreover, transmission parameters of an OFDM based system can be detected blindly if the system is not known to cognitive radio. The capability of identifying ...
