چکیده
In the context of spectrum surveillance (non cooperative context), a robust synchronization procedure is presented, in order to estimate the period symbol and the timing o¤set of a direct sequence spread spectrum signal. Experimental results are given to illustrate the performances of the algorithm.

The aim of this paper is robust identification of smart foam, as an electroacoustic transducer, considering unmodeled dynamics due to nonlinearities in behaviour at low frequencies and measurement noise at high frequencies as existent uncertainties. Set membership estimation combined with model error modelling technique is used where the approach is based on worst case scenario with unknown but...
متن کاملRobust Synchronization to Frequency Selective Fading Channel in OFDM Systems
The synchronization is one of the most important issues in the OFDM systems. Although the cyclic prefix has widely been used for symbol synchronization, it may not provide performance robust to the multi-cell environment. Therefore, the training symbol method is usually employed in multi-cell environment. Although the use of matched filter can provide best performance, it may have a problem of ...
