Non-Linear Precoding for OFDM Systems in Spatially-Correlated Frequency-Selective Fading MIMO Channels
— This paper presents non-linear precoding design in closed-loop multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) over spatiallycorrelated,...

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...

Adaptive Precoding for Switching between Spatial Multiplexing and Diversity in MIMO OFDM with Transmit Antenna and Path Correlat
Abstract— The path and antenna correlations significantly degrade the system capacity in spatially-multiplexed multiple-input multiple-output (MIMO) orthogonal frequency-divisio...

Impact of Correlation on Linear Precoding in QSTBC Coded Systems with Linear MSE Detection
— In this paper, we study a wireless multiple-input multiple-output system in a Rayleigh flat-fading environment with correlation among the transmit antennas. We assume that the...

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...
