Abstract :
Link layer abstraction is crucial both the cross layer simulation and design and the interface to complete a system level simulator. The calibration takes an important role within this design. In this paper we have used several kinds of algorithms like EESM, CESM and LESM for the instantaneous channel, calibration and evaluation of the link level interface in WiMAX system 802.16e. In order to have real world situations, we are also using the adaptative modulation and coding (AMC), hybrid automatic repeat request (H-ARQ) and PUSC/FUSC permutation besides of OFDM systems. Plenty of simulations were made for evaluate the different algorithms and the results show that EESM has better accuracy that the others.
