Abstract
According to the invention, the method comprises the steps of calculating and evaluating the auto-correlation functions and/or cross-correlation functions of N possible secondary synchronization codes (SSC) and the primary synchronization code (PSC) and choosing the M secondary synchronization codes (SSC) amongst said N possible secondary synchronization codes (SSC) so that said the M chosen secondary synchronization codes (SSC) have at least one of the statistical properties of their auto-correlation function and cross-correlation function that is best in term of detection, and allocating a sub-set of said M secondary synchronization codes (SSC) comprising K secondary synchronization codes (SSC) to said base station.
