PROCESS FOR SLOT SYNCHRONIZATION OF THE P-SCH SEQUENCE IN A UMTS COMMUNICATION SYSTEM, AND A RECEIVER FOR THE SAME

摘要

A Process for achieving slot synchronization of the P-SCH sequence in a UMTS communication system, involving the step of
- receiving (41) said signal including a synchronization sequence (PSCH);
- performing a correlation (42) of each received sample with a known synchronization sequence (P-SCH) in order to generate a correlation profile;
- determining (43) the level of noise and computing a first threshold;
- suppressing (44) any peaks within said correlation profile having a magnitude inferior to said first threshold;
- detecting (45) the persistent local maximum peaks over a period of N slots;
- applying a predetermined mask positioned with respect to said persistent peaks and associated to at least one second threshold value distinctive from said first threshold.
