Abstract:
A method for use in selecting one of multiple nearby base stations to facilitate communication over a wireless network, where each base station transmits a pilot signal that includes a spreading signal transmitted at one of many possible phase offsets, the method comprising:(a) selecting an initial one of the possible phase offsets of the spreading signal; (b) correlating a received signal against the spreading signal at consecutive ones of the possible phase offsets, beginning at the selected initial phase offset, 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; (c) thereafter selecting a non-consecutive one of the possible phase offsets of the spreading signal; and (d) correlating the received signal against the spreading signal at the selected 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.
