MIMO-OFDM Communication System: Channel Estimation and Wireless Location

Author Name : Kajal, Ms Bhawna

ABSTRACT: In this new information age, high data rate and strong reliability features our wire-less communication systems and is becoming the dominant factor for a successful deployment of commercial networks. MIMO-OFDM (multiple input multiple output-orthogonal frequency division multiplexing), a new wireless broadband technology, has gained great popularity for its capability of high rate transmission and its robust-ness against multi-path fading and other channel impairments. A major challenge to MIMO-OFDM systems is how to obtain the channel state in-formation accurately and promptly for coherent detection of information symbols and channel synchronization.
