Abstract :
We present a new methodology for constructing accurate physical-layer (radio link) performance models for dynamic wireless network system simulations. Our approach emphasizes the consistent treatment of the residual fading effects caused by inaccurate channel estimation across slot, transmission time interval, and hybrid automatic repetition request levels. The proposed performance models can he implemented using simple manipulations of certain pre-calculated values. Numerical results are provided to illustrate the accuracy for individual models as well as for multiple models combined together.
