Abstract :
This paper studies how to estimate the packet error rate (PER) of a HIPERLAN/2 link without using detailed link-level simulations. This is useful mainly for speeding up system-level simulations. An extension to MIMO is also considered. Two different 2D lookup table methods are evaluated, that take both the empirical mean sub-carrier quality across the frequencies and the frequency variability into account. Numerical validations show that these new methods are able to estimate the average PER more accurately than using a traditional 1D mapping. It is shown that these PER estimation methods are critical when characterizing the performance of MIMO transmission schemes where the frequency properties of the effective channel may deviate significantly from the SISO case.
