Low-rate Feedback for Real Measured Temporally Correlated Mimo Channels
نویسندگان
چکیده
This work presents a summary of a proposal for a feedback scheme in a multi-input-multi-output (MIMO) communication system based on a differential quantization strategy applied to the channel response. The performance of this scheme is evaluated using real data and channel measurements obtained with the Eurecom’s MIMOOpenAir Sounder (EMOS). More concretely, the impact of having a delay in the feedback link is also studied in terms of a loss of performance in the communication through several simulation results. Topics: Precoding and limited feedback, Multi-antenna channel measurements, MIMO systems.

Compressed Sensing Based Rotative Quantization in Temporally Correlated MIMO Channels
Channel adaptive transmission requires knowledge of channel state information at the transmitter. In temporally correlated MIMO channels, the correlation can be utilized to reduce feedback overhead and improve performance. In this paper, Compressed Sensing (CS) methods and rotative quantization are used to compress and feedback channel state information for MIMO systems as an extension work of ...

متن کاملOn Optimizing Feedback Interval for Temporally Correlated MIMO Channels With Transmit Beamforming And Finite-Rate Feedback
Assuming perfect channel state information (CSI), a receiver in a point-to-point MIMO channel can compute the transmit beamforming vector that maximizes the transmission rate. For frequencydivision duplex, a transmitter is not able to estimate CSI directly and has to obtain a quantized transmit beamforming vector from the receiver via a rate-limited feedback channel. We assume that time evoluti...
متن کاملCombining Long-term and Low-Rate Short-term Channel State Information over Correlated MIMO Channels
A simple structure to exploit both long-term and partial short-term channel state information at the transmitter (CSIT) over a family of correlated multipleantenna channels is proposed. Partial short-term CSIT in the form of a weighting matrix is combined with a unitary transformation based on the long-term channel statistics. The heavily quantized feedback link is directly optimized to maximiz...
متن کاملPerformance of Antenna Selection for MIMO-OFDM Systems Based on Measured Indoor Correlated Frequency Selective Channels
This paper presents and compares antenna selection strategies for frequency selective MIMO-OFDM channels. Real channels are measured, and used to evaluate performance. Results for simulated TGn channel models are also presented. We show that the capacity gain predicted from the simulated channels, is significantly lower than can be achieved over real channels. This supports the use of antenna s...
