摘要：
Effective C/N0(carrier-to-noise ratio) is an important index of GNSS (global navigation satellite system) receiver data demodulation and tracking performance. During past years, analysis of interferences effects on effective C/N0 have been put forward. However, effective C/N0 limits analysis hasn't been presented. Thus, effective C/N0 limits were analyzed. The theory model of effective C/N0 and BER (bit error ratio) were derived in the presence of CWI(continuous wave interference), and results show that effective C/N0 fails to evaluate data demodulation performance under specific condition. Then, the mechanism of effective C/N0 malfunction was elaborated and the application condition of effective C/N0 was presented. Finally, theory analysis is verified by simulations. © 2017, NUDT Press. All right reserved.
