Abstract

A mobile wireless transceiver selects one of multiple nearby base stations to facilitate communication over a wireless network. Each base station transmits a pilot signal that includes a spreading signal transmitted at one of many possible phase offsets. The wireless transceiver selects an initial one of the possible phase offsets of the spreading signal and then correlates a received signal against the spreading signal at consecutive ones of the possible phase offsets. Correlation begins at the selected initial phase offset and continues until a component of the received signal and the spreading signal are aligned, indicating the detection of the pilot signal from one of the base stations. The transceiver then selects a non-consecutive one of the possible phase offsets of the spreading signal and correlates the received signal against the spreading signal at this non-consecutive phase offset to determine whether any other component of the received signal is aligned with the spreading signal at the selected non-consecutive phase offset.
