      In this paper, we derive multiple antenna transmission strategies in the presence of limited channel information at the transmitter and the receiver. In particular, we look at the cases of complete channel information, ...
    • DESIGN OF MULTIVARIABLE FEEDBACK CONTROLLERS: ITALIC-L(1)-OPTIMAL SYSTEMS 

      DAHLEH, MUNTHER ABDULLAH (1987)
      This thesis treats the following problem: Given a multivariable linear time-invariant plant, we want to design a feedback controller in such a way that the closed loop system is internally stable and the output tracks an ...
    • DESIGN OF OPTIMAL DIGITAL FILTERS (APPROXIMATION, CHEBYSHEV, LINEAR PHASE, MINIMUM PHASE, COMPLEX DOMAIN) 

      CHEN, XIANGKUN (1986)
      Four methods for designing digital filters optimal in the Chebyshev sense are developed. The properties of these filters are investigated and compared. An analytic method for designing narrow-band FIR filters using Zolotarev ...
    • Design of Optimal Feature Extractors by Mathematical Programming Techniques 

      de Figueiredo, Rui J.P. (1976-06-20)
      In an automatic pattern recognition system, the processor that selects and measures features fo the data, on the basis of which classification is made, is called a "feature selector" or "feature extractor". This paper ...
    • Design of oversampled multichannel filter banks 

      von Borries, Ricardo Freitas (2005)
      This thesis introduces a general approach for the design of oversampled multichannel filter banks including one-dimensional and nonseparable multidimensional filter banks, as well as filter banks with linear phase and ...
    • Design of prototyping platforms for multiple antenna wireless communications 

      Murphy, Patrick O. (2005)
      As the demand for higher performance wireless communications continues to grow, novel algorithms have been developed which provide increased performance and efficiency. One such class of algorithms involves the use of ...
    • DESIGN OF ROBUST FEEDBACK SYSTEMS FOR ROBOT ARM MANIPULATOR 

      OUDJEHANE, BADREDDINE (1986)
      The principal problem is the control of a nonlinear system with uncertainty. We will consider a robot manipulator system, which is nonlinear, and uncertain (unknown parameters and modeling errors). Our goals are to come ...
    • Design of Space Time Codes With Optimal Coding Gain
