This study proposes a class of variable structure stabilizing laws which make the closed-loop system be capable tolerating abnormal operation actuators within pre-specified subset actuators. The ranges acceptable change in control gain magnitude that preserves system's stability are estimated for whole set These shown to able made larger than those obtained by linear quadratic regulator (LQR) reliable design (Veillette, 1995, and Liang, 2000) choice parameters. Besides, this approach does...
Transmit beamforming (BF) and receive combining are simple popular methods for performance enhancement in multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems. In this paper, we propose a novel single-data stream, time-domain BF (TD-BF) scheme MIMO-OFDM systems which uses cyclic filters (C- BFFs). Assuming perfect channel state information (CSI) at the transmitter, C-BFFs optimized two different criteria, namely, maximum average mutual (AMI) per...
In this paper, we propose frequency-domain (FD) and time-domain (TD) beamforming (BF) schemes for cooperative orthogonal frequency division multiplexing (OFDM) networks with multiple amplify-and-forward relays. Whereas FD-BF the BF weights are applied in FD, TD-BF cyclic filters (C-BFFs) used on TD signal avoiding discrete- time Fourier transform operations at relays drastically reducing required amount of feedback from receiver to Adopting average mutual information (AMI) per sub-carrier as...

In this paper, we consider minimum bit error rate (BER) beamforming (BF) for multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems. particular, assuming perfect channel state information (CSI) at the transmitter optimize cyclic BF filters (C-BFFs) minimization of average BER and maximum sub-carrier BER, respectively. If C-BFF length L <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">g</sub> is equal to...
A quasi-sliding-mode control law is proposed for a class of discrete-time nonlinear systems concerning system stabilisation and chatter alleviation. An illustrative example also given to demonstrate the use benefits scheme.
