Abstract
The invention relates to a method for synchronizing a radio terminal in a radio-communication network with a received signal flow comprising a predefined synchronization sequence repeated at predefined time intervals. According to the invention, the method consists in generating correlation profiles at the radio terminal by correlating a part of said signal flow with the synchronization sequence to reveal correlation peaks and accumulating as many correlation profiles as necessary, until a threshold level is reached by at least the largest correlation peak. The threshold level is updated, during the accumulation, depending on a background noise level estimated in the signal flow to dynamically determine if the synchronization sequence has been detected at the radio terminal.
