Abstract: Orthogonal frequency division multiplexing (OFDM) is one of the modulation scheme, used for high speed mobile communication. However, fast time varying multipath channels leads to loss of orthogonality of subcarriers and introduces inter carrier interference (ICI). In this study, MMSE equalizer is implemented to remove ICI. The information of Channel Impulse Response (CIR) required for equalizer is estimated on every subcarrier using time domain Kalman Filter. In further study, decision feedback equalizer will be implemented of which performance will be compared on the basis of bit error rate (BER) with that of MMSE equalizer

Abstract: Virtualization has moved to the forefront of many organizations\' IT agendas, because it reduces both the number of physical servers required and the associated costs. This independent study by the International Technology group found IBM PowerVM more cost-competitive over time, compared to VMware, in terms of IT costs and the costs of downtime.And its show independent study can change IT sector
