A Robust Estimation and Tracking of Channel for Time and Frequency Selective MIMO-OFDM Systems
International Journal of Intelligent Engineering and Systems
Due to the higher data transmission networks and maximum efficiency, multiple-input-multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) has become most vital wireless communications system in nowadays. Accurate estimation of channel under severe time and frequency selective fading channels has been required by these MIMO-OFDM systems for enabling high practical mobility. Established methods trust on nonrealistic estimations or result in impractical complexities. In this, wedoi:10.22266/ijies2018.0630.19 fatcat:l3oiewnpmnd57huq65bab54gae
