MIMO – OFDM : Technology for high speed wireless Transmission. Abstract:-The demand for increased channel capacity in wireless and mobile communication has been rapidly increasing due to multi fold increase in demands of mobile data and multimedia services. In the present scenario, high data rate are provided by
ABSTRACT. In this paper, we propose an enhancement of a blind channel estimator based on a subspace approach in a MIMO OFDM context (Multi Input Multi Output Orthogonal Frequency Division Multiplexing) in high mobility scenario. As known, the combination between the MIMO context and the OFDM system has.

14 Mar 2006 The demand of wireless communications is constantly growing. • Future wireless systems will require a much more efficient use of the available frequency resources. • MIMO is known to boost channel capacity. • For high-data rate transmissions, the MIMO channel is frequency selective (multipath). • OFDM
ABSTRACT | This overview portrays the 40-year evolution of orthogonal frequency division multiplexing (OFDM) research. The amelioration of powerful multicarrier OFDM arrangements with multiple-input multiple-output (MIMO) systems has nu- merous benefits, which are detailed in this treatise. We continue by
(STF) coding for MIMO-OFDM systems. Per- formance results show that STF coding can achieve the maximum diversity gain in an end- to-end MIMO-OFDM system over broadband wireless channels. Furthermore, for orthogonal frequency division multiple access (OFDMA), we propose a multiuser SF coding scheme that.

The major challenges in future wireless communications system design are increased spectral effi- ciency and improved link reliability. The wireless channel constitutes a hostile propagation medium, which suffers from fading
