Abstract
Wireless communication synchronization at a wireless signal receiver is described. A wireless signal received may be a spread spectrum signal containing a periodic extension of a primary code, a periodic extension of a secondary code, and a data portion. The receiver may determine a first chip sequence representative of the secondary code by extraction of the primary code and the data portion from a first received wireless signal. The receiver may further determine, from a second received wireless signal, a second chip sequence representative of the secondary code by extraction of the primary code from the second received wireless signal. The receiver may identify a phase offset associated with the received wireless signals by analyzing the first chip sequence and the second chip sequence.
