Abstract

A User Equipment (UE) has as circuit that performs the acquisition for the low chip rate option of the Universal Mobile Telecommunication System (UMTS) Time Division Duplex (TDD) standard as formulated by the Third Generation Partnership Project (3GPP). The present invention implements the detection (10) of the basic SYNC code; the determination (20) of the midamble used and the detection (30) of the superframe timing based on SYNC code modulation sequence. This enables reading of a full Broadcast Channel (BCH) message.
