Broadband MIMO-OFDM wireless communications [PDF]
Proceedings of the IEEE, 2004 Orthogonal frequency division multiplexing (OFDM) is a popular method for high data rate wireless transmission. OFDM may be combined with antenna arrays at the transmitter and receiver to increase the diversity gain and/or to enhance the system capacity on time-varying and frequency-selective channels, resulting in a multiple-input multiple-output ...

MIMO-OFDM Crystallized Rate Regions
, 2010 In this paper, we introduce the generalization of the con- cept of crystallized rate regions for MIMO-OFDM trans- mission. The extension from the OFDM and MIMO case to MIMO-OFDM scenario of the time-sharing convex hull of achievable rates is discussed ...

Fast Link Adaptation for MIMO OFDM [PDF]
IEEE Transactions on Vehicular Technology, 2010 We investigate link-quality metrics (LQMs) based on raw bit-error-rate, effective signal-to-interference-plus-noise ratio, and mutual information (MI) for the purpose of fast link adaptation (LA) in communication systems employing orthogonal frequency-division multiplexing and multiple-input–multipleoutput (MIMO) antenna technology.

A Transmitter Design for the Multi-beam CC-OFDM Azimuth Scanning MIMO Radar
IEEE Access, 2022 A conventional phased array radar provides a high gain by transmitting coherent signals over a large number of antenna elements. However, it does not provide a full time-on-target because it produces a beam that scans the whole angular view of the radar.
