MIMO Radar with Colocated Antennas

IEEE Signal Processing Magazine, 2007
We have provided a review of some recent results on the emerging technology of MIMO radar with colocated antennas. We have shown that the waveform diversity offered by such a MIMO radar system enables significant superiority over its phased-array counterpart, including much improved parameter identifiability, direct applicability of adaptive techniques

MIMO CDMA antenna systems

2000 IEEE International Conference on Communications. ICC 2000. Global Convergence Through Communications. Conference Record, 2002
We investigate the performance of a DS/CDMA system with multiple-input multiple-output (MIMO) antenna processing in the downlink. We formulate the weights for the transmit and receive antennas by trying to obtain the optimum signal-to-interference-plus-noise ratio (SINR) in a frequency selective fading channel. The gain of our MIMO CDMA system with the

On optimum MIMO with antenna selection

IEEE Communications Letters, 2002
Wireless communication systems with transmit and receive antenna arrays are studied when antenna selection is used. A case with very limited feedback of information from the receiver to the transmitter is considered, where the only information fed back is the selected subset of transmit antennas to be employed.

Antenna selection in MIMO systems

IEEE Communications Magazine, 2004
Multiple-antenna systems, also known as multiple-input multiple-output radio, can improve the capacity and reliability of radio communication. However, the multiple RF chains associated with multiple antennas are costly in terms of size, power, and hardware. Antenna selection is a low-cost low-complexity alternative to capture many of the advantages of

A novel parasitic-MIMO antenna

2006 IEEE Antennas and Propagation Society International Symposium, 2006
Based on the results of a numerical investigation, the performance of the parasitic-MIMO system can be improved with the introduction of simple and cheap parasitic elements. The introduction of the switchable parasitic elements help to modify the channel introducing a sort of "controllable scatterers" in the close proximity of the active elements.
