Technical paper on MIMO - OFDM: Technology for high speed wireless communication

摘要

The demand for increased channel capacity in wireless and mobile communication has been rapidly increasing world wide due to multi fold increase in mobile telephony, High speed Internet users and multimedia services coupled with a limited spectrum. In the present scenario, high data rate is required in WLAN , Wi-Max and LTE/ LTE advanced-4G. In this paper MIMO antenna technique and OFDM has been described. Industry standards, present applications and further research has also been taken up. MIMO system with OFDM gives higher gain by using the direct and the reflected signals thus facilitating the transmission at high data rate.
