Abstract

DC60 Each base station transmits a TDM-1 pilot signal, which has multiple instances of a sequence of -1 lead signals, which are generated with a PN1 sequence and a TDM2 lead signal. Have an instance At least one of the leading signal sequences -2. Which was generated with a PN 2 sequence.Each base station was assigned a specific PN2 sequence that was identifiable to that base station.The terminal device would use the TDM1 lead to Check for the existence of a signal And uses TDM2 navigation signals to identify base stations and achieve precise timing for signal detection. The terminal device performs a delay correlation with the sampling signal. That receives it and determines whether the signal is available or not If the signal is detected Terminal device This will perform a direct correlation on this incoming sampling signal with a PN 1 sequence for a different time offset K1 and specify the number of strongest TDM1 lead signal instances. K2 for time synchronization This end device will perform a direct correlation on This incoming sampling signal is received with a PN2 sequence to detect the TDM-2 pilot signal.Each base station transmits the TDM-1 pilot signal, which has multiple instances of the pilot-sequence. 1, which is generated with a PN 1 sequence and a TDM signal 2, which has an instance At least one of the leading signal sequences -2.
