Outage Constrained Robust Transmit Optimization for Multiuser MISO Downlinks: Tractable Approximations by Conic Optimization

Further Simulation Results for “Outage Constrained Robust Transmit Optimization for Multiuser MISO Downlinks: Tractable Approximations by Conic Optimization” Technical Report

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-m...

Tractable Approximations to Robust Conic Optimization Problems

In earlier proposals, the robust counterpart of conic optimization problems exhibits a lateral increase in complexity, i.e., robust linear programming problems (LPs) become second order cone problems (SOCPs), robust SOCPs become semidefinite programming problems (SDPs), and robust SDPs become NP-hard. We propose a relaxed robust counterpart for general conic optimization problems that (a) prese...

Distributionally Robust Optimization and Its Tractable Approximations

In this paper, we focus on a linear optimization problem with uncertainties, having expectationsin the objective and in the set of constraints. We present a modular framework to obtain an approx-imate solution to the problem that is distributionally robust, and more flexible than the standardtechnique of using linear rules. Our framework begins by firstly affinely-extending the ...

A novel generalized optimization criterion for transmit signal design in Joint Transmission (JT) multiuser downlinks

Joint Transmission (JT), a novel downlink transmission scheme, was introduced and described in recent papers. The crux of JT consists in exploiting channel state knowledge at the base stations to jointly generate a common transmit signal for the support of all mobile terminals, with the aim to directly eliminate intersymbol interference and intracell multiple access interference while transmitt...
