Abstract

Pilot Channel without navigation message modulation is added in next generation GNSS for enhancing the acquisition performance in challenge environment. The pre-detection integration time of pilot channel is potential to exceed the bit width, so the receiver could obtain better acquisition sensibility. However, the benefit from pilot channel has not been thoroughly analyzed. The equivalent ideal detector factor is used to compare the performance of different power allocation options of data and pilot channel. The results show that when the data and pilot channel has the same power, the acquisition sensibility is not better than that of traditional signal in normal conditions. The conclusion has significance on the BDS modernized signal design.
