It is now well known that employing channel adaptive signaling in wireless communication systems can yield large improvements in almost any performance metric. Unfortunately, many kinds of channel adaptive techniques have been deemed impractical in the past because of the problem of obtaining channel knowledge at the transmitter. The transmitter in many systems (such as those using frequency division duplexing) can not leverage techniques such as training to obtain channel state information…

Limited Feedback in Wireless Communications and Networks

This paper introduces the limited feedback general procedure and overview its applications in multicarrier wireless communications, Multi-Input and Multi-Output (MIMO) wirelesscommunications, cooperative communications, underwater acoustic communications and wireless networks.

Data Transmission in the Presence of Limited Channel State Information Feedback

Two different approaches, namely, quantized CSI feedback and automatic repeat request (ARQ) are considered, providing the imperfect channel quality information at the transmitter, to increase the transmission reliability in the absence of the transmitter CSI.

Wireless Communication over Time-Varying Channels With Limited Feedback

This thesis considers a single-link MIMO system, and investigates different scenarios where CSI knowledge at the transmitter plays a paramount role, and proposes the use of predictive vector quantization to exploit the time correlation to improve the CSI quantization.

Does Frequent Low Resolution Feedback Outperform Infrequent High Resolution Feedback for Multiple Antenna Beamforming Systems?

It is shown that in the large system limit the feedback update periods required for both the average effective SNR and capacity loss converge to the same bound, verifying that infrequent high resolution feedback is sometimes preferable to frequent low resolution feedback.

Limited Feedback Techniques in Multiple Antenna Wireless Communication Systems

This thesis examines CSI inaccuracies due to codebook quantization errors and investigates several other aspects of limited feedback in SU, MU and multicell wireless communication systems with various channel models, and proposes various adaptive scaling techniques for differential codebooks where packing density of codewords in the differential codebook are altered according to the channel condition.

Multiple-antenna Communications with Limited Channel State Information

This thesis focuses on the optimal design of limited feedback systems for three types of communication channels: the relay channel, the singleuser point-to-point channel, and the multiuser broadcast channel.

Performance of Multi-antenna Wireless Systems with Channel Estimation Error

Water-filling is a strategy that achieves the maximum data rate in such multiple-input multiple-output (MIMO) systems when perfect CSI is available at both the transmitter and the receiver.

Wireless interference networks with limited feedback

A new feedback and transmit strategy which combines flexibility and robustness needed for efficient and reliable communication is developed and it is proved that it has better scaling properties compared to classical results on the limited feedback problem in the broadcast channel.

Utilizing temporal correlation in multiuser MIMO feedback

A limited feedback approach utilizing the temporal channel correlation information in multiuser downlink MIMO systems is proposed and the impact of the feedback amount on sum-rate performance when a zero-forcing beamformer is used at a base station is analyzed.

On the Throughput of Wireless Communication With Combined CSI and H-ARQ Feedback

The simulation results show that, besides signal-to-noise ratio (SNR) and Doppler, the optimal pilot overhead depends on whether the authors are using rate/power adaptation and the number of re-transmissions, and it is proved that in slow-fading channels with high SNR regimes, varying the rate provides the best throughput.



Feedback gain in multiple antenna systems

The results demonstrate that for block fading channels, sending a periodic preamble and causally receiving channel state information via a feedback channel can lead to substantial gains in the outage performance over any nonfeedback scheme, and can be translated into improvements in frame error rate performance of systems using space-time codes.

Adaptive Signaling Based on Statistical Characterizations of Outdated Feedback in Wireless Communications

Numerical results will demonstrate in both the single-antenn and multiple-antenna cases that such an approach provides a robust method for improving system data rate versus the standard practice of employing link margin to compensate for such uncertainties.

What is the value of limited feedback for MIMO channels?

Performance results show that even a few bits of feedback can provide performance close to that with full channel knowledge at the transmitter.

Optimal Signaling and Selection Verification for Single Transmit-Antenna Selection

It is shown that optimizing the signaling assignment, which maps the antenna indices to the feedback codewords, improves performance without introducing any additional redundancy, and optimal and suboptimal, blind and nonblind selection-verification methods are developed.
