This communication addresses the problem of the recognition systems based on OFDM (Orthogonal Frequency-Division Multiplexing). Such a problem arises in various fields of applications among cognitive radio and military applications. We present a new blind discrimination algorithm between the standards: the 3GPP/LTE (3rd Generation Partnership Project/Long Term Evolution, the WiMax IEEE 802.16 (Worldwide...
In the cognitive radio context, sensing process is a crucial task. The cognitive devise has to be able to detect and to identify several radio systems. As more standards are now based on OFDM modulation the paper aims with the parameters estimation of such a modulation. All actual OFDM-based standards differ from their subcarrier spacing therefore it will be ingenious to focus on this parameter to...
