Abstract :
Behavioral-level simulation is a widely-used design tool for digital wireless communication systems operating at RF/microwave frequencies. However, success in using this tool depends substantially on the simulation accuracy. We consider some factors contributing to the accuracy of behavioral-level simulation. A key factor is an accurate measurement of envelope AM-AM and AM-PM transfer functions and an accurate computation of instantaneous transfer functions. Some practical recommendations how to improve the simulation accuracy are given
