Preamble-Based Synchronization For Ofdm/Oqam Systems
2011
Zenodo
Preserved Fulltext
Publication in the conference proceedings of EUSIPCO, Barcelona, Spain, 2011 ...
For example, in [6, 7, 8] blind CFO estimators that exploit the second-order cyclostationarity of the transmitted OFDM/OQAM signal are proposed while in [9] a synchronization scheme for data-aided ...
Unlike OFDM, OFDM/OQAM systems do not require the presence of a CP in order to combat the effects of frequency selective channels. ...

In such a scenario, the signals transmitted by the UAV and the malicious mobile jammer undergo both time dispersion due to multipath propagation effects and frequency dispersion caused by their mobility ...
Amplitudes, phases, time delays, and Doppler shifts - required to implement the proposed detection strategy - are blindly estimated from data through the use of algorithms that exploit the almost-cyclostationarity ...
To cope with the time-dispersive nature of the channel, the UAV employs OFDM transmission with OFDM symbol period T and sampling period T c . ...

After CFO and STO correction, the preamble can be reused to estimate the channel. Unlike most current techniques, the CFO and STO estimation occurs in the frequency domain. ...
It is based on a relatively long preamble in order to improve the CFO estimation performance as well as avoid interference coming from the data following this preamble. ...
