On Chernoff Lower-Bound of Outage Threshold for Non-Central $χ^2$-Distributed Beamforming Gain in URLLC Systems

no code implementations28 Dec 2023 Jinfei Wang, Yi Ma, Rahim Tafazolli, Zhibo Pang

The cumulative distribution function (CDF) of a non-central $\chi^2$-distributed random variable (RV) is often used when measuring the outage probability of communication systems.

On Chernoff Lower-Bound of Outage Threshold for Non-Central $χ^2$-Distributed MIMO Beamforming Gain

no code implementations24 Aug 2023 Jinfei Wang, Yi Ma, Rahim Tafazolli

The cumulative distribution function (CDF) of a non-central $\chi^2$-distributed random variable (RV) is often used when measuring the outage probability of communication systems.

Sherman-Morrison Regularization for ELAA Iterative Linear Precoding

no code implementations26 Jan 2023 Jinfei Wang, Yi Ma, Na Yi, Rahim Tafazolli

The design of iterative linear precoding is recently challenged by extremely large aperture array (ELAA) systems, where conventional preconditioning techniques could hardly improve the channel condition.

Constellation-Oriented Perturbation for Scalable-Complexity MIMO Nonlinear Precoding

no code implementations4 Aug 2022 Jinfei Wang, Yi Ma, Na Yi, Rahim Tafazolli, Fei Tong

The basic concept of COP is to apply vector perturbation (VP) in the constellation domain instead of symbol domain; as often used in conventional techniques.

Power Allocation for FDMA-URLLC Downlink with Random Channel Assignment

no code implementations4 Aug 2022 Jinfei Wang, Yi Ma, Na Yi, Rahim Tafazolli

With imperfect CSIT, the proposed approach can still provide remarkable user capacity at limited cost of transmit-power efficiency.

Network-ELAA Beamforming and Coverage Analysis for eMBB/URLLC in Spatially Non-Stationary Rician Channels

no code implementations19 Jan 2022 Jinfei Wang, Yi Ma, Na Yi, Rahim Tafazolli, Fan Wang

Finally, it is shown that the network-ELAA can offer significant coverage extension (50% or more in most of cases) when comparing with the single-AP scenario.

Massive-MIMO MF Beamforming with or without Grouped STBC for Ultra-Reliable Single-Shot Transmission Using Aged CSIT

no code implementations3 Oct 2021 Jinfei Wang, Yi Ma, Na Yi, Rahim Tafazolli, Zhibo Pang

In addition, a combinatorial approach of the MF beamforming and grouped space-time block code (G-STBC) is proposed to further mitigate the detrimental impact of the CSIT uncertainty.
