Abstract：The non-ideal components of the signal generator of a navigation satellite payload can distort the transmitted signal. On the one hand, no applicable analytical model about the ranging performance loss caused by such signal distortions have been established by far. On the other hand, existing simulation studies about the analog distortions of wide-band dual-frequency multiplexing signals are not quite comprehensive. This paper simulates the correlation loss, S-curve bias, and carrier phase tracking bias caused by the combined effects of non-ideal analog components in the payload including the Pre-HPA Filter, High Power Amplifier (HPA), and Output Multiplexer (OMUX), for 4 different dual-frequency multiplexing modulations including AltBOC, TD-AltBOC, ACEBOC and AltLOC, In the simulation, we employ a memory behavioral model of HPA instead a memoryless model, taking the effects of different Pre-HPA filter bandwidth and HPA operating points into account. In addition, the performance loss of the distorted signal relative to the ideal signal is evaluated for both the double sideband and the single sideband pilot tracking methods. The study provides a useful reference for not only the comparison and evaluation of different modulation signals but also the optimization design of the payload signal generator.
