چکیده
This technical report serves to provide further simulation results for the paper “Outage constrained robust transmit optimization for multiuser MISO downlinks: Tractable approximations by conic optimization”. In addition to the rate constrained formulation, which is the main focus of the aforementioned main manuscript, we also demonstrate how the proposed methods can be used to tackle the max-min fairness formulation and the achievable rate region characterization problem.

Robust Linear MIMO in the Downlink: A Worst-Case Optimization with Ellipsoidal Uncertainty Regions
This paper addresses the joint robust power control and beamforming design of a linear multiuser multiple-input multiple-output (MIMO) antenna system in the downlink where users are subjected to individual signal-to-interference-plus-noise ratio (SINR) requirements, and the channel state information at the transmitter (CSIT) with its uncertainty characterized by an ellipsoidal region. The objec...
متن کاملProbability-constrained Power Optimization for Multiuser MISO Systems with Imperfect CSI: A Bernstein Approximation Approach
We consider power allocations in downlink cellular wireless systems where the basestations are equipped with multiple transmit antennas and the mobile users are equipped with single receive antennas. Such systems can be modeled as multiuser MISO systems. We assume that the multi-antenna transmitters employ some fixed beamformers to transmit data, and the objective is to optimize the power alloc...

In this paper, we studies robust downlink beamforming for a multiuser multiple-input single-output (MISO) simultaneous wireless information and power transfer (SWIPT) system when only imperfect knowledge of the channel state information (CSI) is available at the transmitter. Specifically, we exploit two different models to describe CSI errors: a) deterministic bounded and b) stochastic random. ...

In this paper, we consider robust non-linear precoding for the downlink of a multiuser multiple-input single-output (MISO) communication system in the presence of imperfect channel state information (CSI). The base station (BS) is equipped with multiple transmit antennas and each user terminal is equipped with a single receive antenna. We propose two robust Tomlinson-Harashima precoder (THP) de...
متن کاملOn safe tractable approximations of chance constraints
A natural way to handle optimization problem with data affected by stochastic uncertainty is to pass to a chance constrained version of the problem, where candidate solutions should satisfy the randomly perturbed constraints with probability at least 1− . While being attractive from modeling viewpoint, chance constrained problems “as they are” are, in general, computationally intractable. In th...
