Abstract
For high capacity demand for 4G broadband multimedia and internet services with high quality of service (QoS), multiple input multiple output (MIMO) transmission methods are exploited for high speed machine to machine communication. In order to mitigate the fast fading multipath effects, orthogonal frequency division multiplexing (OFDM) is used as modulation technique for MIMO systems. Time-domain channel characteristics are used to make efficient channel state information (CSI) available at the transmitter side. In this paper Windowed-DFT technique is optimized for channel estimation and the performance and complexity are determined. Computer Simulations are used to show the effect of channel filter length and the number of multipath channel taps.
