11. Development and evaluation of methods for control of multiple-input multiple output systems
Sammanfattning : In control, the most common type of system is the multiple-input multiple-output (MIMO) system, where the same input may affect multiple outputs, or conversely, the same output is affected by multiple inputs. In this thesis two methods for controlling MIMO systems are examined, namely linear quadratic Gaussian (LQG) control and decentralized control, and some of the difficulties associated with them.

12. Innovative Security Business : Innovation, Standardization, and Industry Dynamics in the Swedish Security Sector, 1992–2012
Sammanfattning : The overall aim of this dissertation is to generate new knowledge on innovation output and standardization in industries where innovation output typically is considered sparse. This is done through the longitudinal study of the Swedish security guard industry and security sector 1992-2012. LÄS MER
13. Capacity-constrained production-inventory systems : using Laplace transforms and input-output analysis
Sammanfattning : This work is concerned with multi-level, multi-stage capacity-constrained production-inventory problems. The aim is to provide a contribution to a theoretical background for Material Requirements Planning (MRP) using the Laplace Transform approach and Input-Output Analysis. LÄS MER
14. Detection for multiple input multiple output channels : analysis of sphere decoding and semidefinite relaxation
Sammanfattning : The problem of detecting a vector of symbols, drawn from a finite alphabet and transmitted over a multiple-input multiple-output (MIMO) channel with Gaussian noise, is of central importance in digital communications and is encountered in several different applications. Examples include, but are not limited to; detection of symbols spatially multiplexed over a multiple-antenna channel and the multiuser detection problem in a code division multiple access (CDMA) system.

15. Multiple-Input Multiple-Output Radio Propagation Channels : Characteristics and Models
Sammanfattning : In recent years, deploying multiple antennas at both transmitter and receiver has appeared as a very promising technology. By exploiting the spatial domain, multiple-input multiple-output (MIMO) systems can support extremely high data rates as long as the environments can provide sufficiently rich scattering. LÄS MER
