Abstract

In this work the evaluation of LS channel estimation algorithm for MIMO-OFDM system is carried out. The evaluation has been made using specific pilot design rules that guarantee a bounded error level for the estimation. The method is used to estimate the channel matrix. The quality of the method is evaluated, not for a specific channel but in diverse surroundings of mobile representative channels with different characteristics (SUI channels). The evaluation has been made by software simulations and system parameters complying 802.16 standard. Estimation error dependence on the number of pilots used, its design parameters and SNR are obtained.
