  • Signal acquisition performance is evaluated for the tiered polyphase code (TPC) which is proposed as a ranging signal structure for global navigation satellite systems (GNSSs). Compared to the tiered code (TC) which is adopted in European Union's GALILEO system, the TPC shows robust performance to frequency offset in acquiring signal. Therefore the TPC should have SNR gain in signal acquisition and can reduce computational complexity in the receiver. In this paper, we compare the signal detection probability of the TC and TPC under the same receiver architecture and GALILEO E5a-I signal parameters.
