A pilot channel:
  • Assist mobile station to be connected with CDMA network
  • Handles multi-path searching
  • Provide the phase reference for coherent demodulation and help the mobile station estimate the transmission power
  • The mobile station measures and compares the pilot channel powers from the base stations during the handoff
  • Forward pilot channel is spread over W0 and modulated with short code directly
  • BTS transmits the pilot channel continuously.
