This page describes CPICH or common pilot channel with respect to WCDMA/UMTS system.
The pilot channel is used by the base station to provide a reference to all mobile stations and to aid the channel estimation at the terminals. It has a predefined bit sequence (all 1s) which is scrambled with the cell-specific primary scrambling code.
There are two types of CPICH: primary and secondary.
