The message transmitted by the pilot channel is a constant stream of binary zeros and is spread by Walsh code zero, which also consists of 64 binary zeros. Therefore, the modulated pilot signal is nothing but the short code, which can be utilized by the receiver to detect the presence of a CDMA signal and then track it. The fact that the pilot signal is data‐less allows for longer integration time. The receiver can differentiate between the BTSs based on their pilot offsets.
