FPCH
Forward Pilot Channel
A direct sequence spread spectrum signal transmitted continuously by each CDMA (Code Division Multiple Access) BS (Base Station). The Forward Pilot Channel allows a MS (Mobile Station) to acquire the timing of the Forward CDMA Channel. It also provides a phase reference for coherent demodulation, and provides a means for comparing the signal strength of neighbouring base stations during the handoff process. The pilot PN (Pseudorandom Noise) sequence time phase is used to identify an individual BS.
