Abstract
A mobile device receives a signal, from a base station, comprising a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The received PSS and SSS are used to acquire cell-specific parameters so as to ensure communicates between the mobile device and the base station. The mobile device correlates the received signal in time domain using signs of each of a plurality of correlation reference sequences (reference PSSs). The mobile device generates sign based correlation reference PSSs using signs of the corresponding reference PSSs, which are generated based on a variety of Zadoff-Chu sequences. The received PSS is detected based on the correlation. No multiplication operations are used in the correlation process. Symbol timing is identified according to the detected PSS. The mobile device uses the identified symbol timing to baseband process the received signal. The received signal is an OFDM signal received over a 3GPP LTE/E-UTRA air interface.
