Method and device for timing synchronization and neighbor scanning for cellular OFDM Systems

摘要

IN THE NAME OF SEQUANS COMMUNICATIONS A device for processing at least an incoming signal in a wireless communication system, said incoming signal being sent by a base station (BS) and comprising successive frames, each of which comprising at least a training symbol correlated to said base station (BS), and a data symbol carrying message data. The device comprises at least:
- a first module (01) digitizing and sampling the incoming signal;
- a second module (02) demodulating said digitized and sampled incoming signal, and generating a corresponding frequency domain symbol (R N );
- a timing synchronization and scanning module (10) suitable for detecting at least a time offset (Ä) of said training symbol by using said corresponding frequency domain symbol (R N ); and
- a timing post processing module (20) for processing said timing offset (Ä) and for generating an improved timing offset (Ä r ) used to start the sampling of following incoming signal.
