Outage behavior of slow fading channels with power control using noisy quantized CSIT
The topic of this study is the outage behavior of multiple-antenna slow fading channels with quantized feedback and partial power control. A fixed-rate communication system is con...

Effects of Non-Ideal Channel Feedback on Dual-Stream MIMO-OFDMA System Performance
— In this paper we analyze the downlink OFDMA system-level performances of a 2x2 dual-stream MIMO multiuser transmission scheme under the assumptions of partial and noisy channel...

Optimal Precoder for Rate 1 Space-Time Block Codes
Abstract— Despite primary space-time coding where the channel state information (CSI) is available at the receiver only, the capacity and performance of multiple-input multiple-o...

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...

QRD-Based Precoded MIMO-OFDM Systems with Reduced Feedback
QR decomposition (QRD)-based precoded MIMO-OFDM systems with reduced feedback are proposed to convert the MIMO-OFDM channel into layered subchannels. QRD-M is further combined wit...
