A base station having the strongest downlink signal is identified by
utilizing a unique slope of a pilot tone hopping sequence being
transmitted by a base station. Specifically, base station identification
is realized by determining the slope of the strongest received pilot
signal, i.e., the received pilot signal having the maximum energy. In an
embodiment of the invention, the pilot tone hopping sequence is based on
a Latin Squares sequence. With a Latin Squares based pilot tone hopping
sequence, all a mobile user unit needs is to locate the frequency of the
pilot tones at one time because the pilot tone locations at subsequent
times can be determined from the slope of the Latin Squares pilot tone
hopping sequence. The slope and initial frequency shift of the pilot tone
hopping sequence with the strongest received power is determined by
employing a unique maximum energy detector.
