ABSTRACT :

Orthogonal frequency-division multiplexing is a popular method for high-data-rate wireless transmission. OFDM may be combined with multiple antennas at both the access point and mobile terminal to increase diversity gain and/or enhance system capacity on a time-varying multipath fading channel, resulting in a multiple-inpu ....etc

MIMO


INTRODUCTION
MIMO is an acronym for Multiple Input, Multiple Output and is a significant departure in the architecture and technology from the current SISO (Single Input, Single Output) WLAN products. This is accomplished through the implementation of multiple transmitters and receivers in a single WLAN station, AP or client.
A principle problem in wireless systems is multipath interference. Existing WLAN technologies attempt to compensa ....etc

MIMO Technology for Advanced Wireless Local Area Networks



Wireless LAN Technology Advances

How can this growth continue?
Previous advances have been limited to a single transmitting and receiving radio
The next generation exploits multiple parallel radios using revolutionary class of techniques called MIMO (Multiple Input Multiple Output) to send information farther and faster

ABSTRACT

Multiple-input multiple-output (MIMO) communication techniques make use of multi-element antenna arrays at both the TX and the RX side of a radio page link and have been shown theoretically to drastically improve the capacity over more traditional single-input multiple output (SIMO) systems . SIMO channels in wireless networks can provide diversity gain, array gain, and interference canceling gain among other benets.In addition to these same advantages, MIMO links can offer a multiplexing ....etc

We present a new model for multiple input multiple-output (MIMO) out door wireless fading channels which is more general and realistic than the usual i.i.d. model. We investigate the channel capacity as a function of parameters such as the local scattering radius at the transmitter and the receiver, the distance between the transmit (TX) and receive (RX) arrays, and the antenna beamwidth sand spacing. We point out the existence of pinhole channels which exhibit low fading correlation between antennas but still have poor rank properties and henc ....etc

MIMO RADAR SIGNAL PROCESSING:MIMO as a Distributed Radar System
ABSTRACT:

Multiple-input multiple-output (MIMO) radar has been receiving increasing attention in recent years from researchers, practitioners, and funding agencies. MIMO radar is characterized by using multiple antennas to simultaneously transmit diverse (possibly linearly independent) waveforms and by utilizing multiple antennas to receive the reflected signals. Like MIMO communications, MIMO radar offers a new paradigm for signal processing research. MIMO radar possesses sig ....etc
