Abstract
Due to OFDM importance and efficiency recently all major wireless technologies adapted this technique. Especially in the field wireless broadband i.e. WiMAX OFDM performs the key role. This technology everyday growing and develop very rapidly. In WiMAX evaluation of channel quality and the combine interference of sub-carriers is a big challenge. Effective SINR mapping (ESM) is a method to combine the SINRs of multi-carrier systems. One of the algorithms of effective SINR mapping (ESM) is exponential effective SINR mapping (EESM) which use the calibration constant beta “β”. This calibration constant to be adjusted that the channel model gives the accurate block error rate (BLER) for given modulation and coding schemes (MCS). In the simulation we find some results and plots not just for single input single output (SISO) but also for single input multi output (SIMO) for different modulation and coding schemes in OFDM WiMAX system, and based on that we develop some observations. At the end conclusion of the papers are given for summary.
