چکیده

Massive multiple-input-multiple-output (M-MIMO) features a capability for spatial multiplexing of large number users. This becomes even more extreme in extra-large (XL-MIMO), variant M-MIMO where the antenna array is very size. Yet, problem signal processing complexity further exacerbated by XL size array. The basic boils down to sparse system linear equations that can be addressed randomized Kaczmarz (RK) algorithm. algorithm has recently been applied devise low-complexity receivers; however, it limited fact certain configurations may significantly deteriorate performance RK In this paper, we embrace interest accelerated algorithms and introduce three new RK-based receiver designs. our experiments, methods are not only able overcome previous scheme, but they robust against inter-user interference (IUI) channel matrices arising XL-MIMO regime. addition, show schemes use mechanism similar used successive cancellation (SIC) receivers approximate regularized zero-forcing (RZF) scheme.

A Variable Structure Observer Based Control Design for a Class of Large scale MIMO Nonlinear Systems

This paper fully discusses how to design an observer based decentralized fuzzy adaptive controller for a class of large scale multivariable non-canonical nonlinear systems with unknown functions of subsystems’ states. On-line tuning mechanisms to adjust both the parameters of the direct adaptive controller and observer that guarantee the ultimately boundedness of both the tracking error and tha...

Accelerated first-order methods for large-scale convex minimization

This paper discusses several (sub)gradient methods attaining the optimal complexity for smooth problems with Lipschitz continuous gradients, nonsmooth problems with bounded variation of subgradients, weakly smooth problems with Hölder continuous gradients. The proposed schemes are optimal for smooth strongly convex problems with Lipschitz continuous gradients and optimal up to a logarithmic fac...

Accelerated Parallel Optimization Methods for Large Scale Machine Learning

The growing amount of high dimensional data in different machine learning applications requires more efficient and scalable optimization algorithms. In this work, we consider combining two techniques, parallelism and Nesterov’s acceleration, to design faster algorithms for L1-regularized loss. We first simplify BOOM [11], a variant of gradient descent, and study it in a unified framework, which...

MIMO Receiver Design in Impulsive Noise

Multi-Input Multi-Output (MIMO) receivers have been typically designed and their communication performance studied in the presence of additive white Gaussian noise. While this is an accurate model for the thermal noise present at the receiver, it falls short of modeling the radio frequency interference (RFI) that may affect the transceivers. RFI is a combination of independent radiation events ...
