6. 4. Adaptation in multiple input multiple output systems with channel state information at transmitter

   Author : Jinliang Huang; Svante Signell; Anders Ahlén; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIMO; adaptive modulation; power allocation; spectral efficiency; CSI; Electrical engineering; Elektroteknik;

   Abstract : This thesis comprises two parts: the first part presents channel-adaptive techniques to achieve high spectral efficiency in a single user multiple-input multiple-output (MIMO) system; the second part exhibits a programmable and reconfigurable software-defined-radio orkbench(SDR-WB) in the Matlab/Octave environment that accommodates a variety of wireless applications. In an attempt to achieve high spectral efficiency, an adaptive modulation technique is applied at the transmitter to vary the data rate depending on the channel state information (CSI). READ MORE

7. 5. Resource-Constrained Embedded Control and Computing Systems

   Author : Dan Henriksson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotteknik; reglerteknik; kontroll; Automation; robotics; control engineering; Automatiska system; numerisk analys; system; Datalogi; control; numerical analysis; systems; Computer science; Server control; Simulation tools; Feedback scheduling; Real-time control systems; Resource constraints;

   Abstract : This thesis deals with methods for handling resource constraints in embedded control systems and real-time computing systems. By dynamic feedback-based resource scheduling it is possible to achieve adaptability andincreased performance for these systems. READ MORE
