Abstract  Abstract

A user equipment unit, UE, capable of performing an initial cell search and establishing a communication link with a base station in a communication network, the UE comprising: a first module (12) configured to process a communication signal and assigning an index value to a peak sample of said communication signal, said index value being used to calculate a chip offset of a main randomization code; and a second module (14) configured to use the calculated chip offset to detect a group number of randomization codes, a range offset and a secondary synchronization code of the communication signal; a third module (16) configured to receive the chip offset calculated by the first module (12), and the randomization code group number and the interval offset detected by the second module (14), the third module being ( 16) configured to retrieve a main randomization code from said communication signal based on the chip offset, the randomization code group number and the interval offset; a controller (18) coupled to said first module (12), second module (14) and third module (16), said UE being characterized in that: said controller (18) is configured to control a setting of a search frequency in said UE to allow the third module (16) to recover the main randomization code in said communication signal; including the controller (18): a first buffer (13) configured to store rejected main randomization codes; a second buffer (9) configured to store displacement vectors of rejected chips; and a logical decision circuit (2) configured to determine if the detected randomization code is correct; wherein the first module (12) also includes a mask generator (5), the mask generator (5) of the first module (12) being configured to determine the chips in each interval to be excluded from detection by means of the logical decision circuit (2), determining the excluded chips based on the chip shifts stored in the second buffer (9).
