Synchronization algorithm for LPTV-based spread spectrum signals
Résumé
Linear Periodic Time-Varying (LPTV) filters can be used as a Spread Spectrum (SS) technique. A particular case of such spreading LPTV filters are Periodic Clock Changes (PCCs). When the spreading operation is realized with PCCs, the synchronization algorithm can also be considered as an LPTV problem. In this paper we will focus on the early-late Delay Lock Loop (DLL) algorithm. We show that this technique can be used to achieve synchronization when the spreading operation is realized by a special class of PCCs: matrix interleavers.
