Minimum Distance-Based Limited-Feedback Precoder for MIMO Spatial Multiplexing Systems
— Precoding is a well-known method to reach the promised performance and capacity of multiple-input multipleoutput (MIMO) systems. Recent investigations, when the transmitter has...

Limited Feedback Precoder Design for Spatially Correlated MIMO Channels
Abstract— It is well-known that perfect channel state information (CSI) at the transmitter and the receiver (CSIT/CSIR) can be used to decompose a multi-antenna channel into a ba...

Capacity Analysis of MIMO Systems Using Limited Feedback Transmit Precoding Schemes
This paper employs a high resolution quantization framework to study the effects of finite-rate feedback of the channel state information (CSI) on the performance of multiple-input

Throughput Performance of Pre-coding MIMO Transmission with Multi-Beam Selection
Abstract―We have been proposing multi-beam MIMO (MBMIMO) as an Evolved UTRA downlink MIMO scheme for 3GPP long term evolution (LTE). MB-MIMO is a pre-coding MIMO scheme that uses...
