Linear and Non-Linear Detection for MIMO-OFDM Systems with Linear Precoding and Spatial Correlation
Precoding at the transmitter side facilitates the use of linear MIMO detection schemes, which are attractive for low-complexity receiver implementations. However, their performance...

Optimal Power Allocation for Linear Dispersion Codes Over Correlated MIMO Channels with Channel State Feedback
— The design of spatio-temporal power allocation schemes is considered for space-time coding over spatially correlated multiple-input multiple-output (MIMO) channels. The focus i...

Link Adaptation in Linearly Precoded Closed-Loop MIMO-OFDM Systems with Linear Receivers
Abstract--Upcoming multi antenna systems such as 3GPPLTE employ code book based multi-mode precoding in order to adapt to a wide range of channel conditions. Link adaptation, which...

Nonuniform Array Design for Robust Millimeter-Wave MIMO Links
—Spatial multiplexing for millimeter (mm) wave line of sight (LOS) links potentially enables data rates of the order of 10-100 Gbps. Most prior work in this area has focused on u...
