Performance-Enhancement of Platform-Based, HF Direction-Finding Systems Using Dynamic Mode Selection

Dynamic Sliding Mode Control of Nonlinear Systems Using Neural Networks

Dynamic sliding mode control (DSMC) of nonlinear systems using neural networks is proposed. In DSMC the chattering is removed due to the integrator which is placed before the input control signal of the plant. However, in DSMC the augmented system is one dimension bigger than the actual system i.e. the states number of augmented system is more than the actual system and then to control of such ...

Performance Enhancement of Mimo Systems Using Antenna Selection Algorithm

Multiple-input multiple-output (MIMO) systems are anticipated to be widely employed to address the ever increasing capacity demands for wireless communication systems. MIMO technology is one solution to attain this by transmitting multiple data streams from multiple antennas. Increasing the number of transmit and receive antennas enables to improve system performance , but the multiple RF chain...

Performance of decoupled direction finding based on blind signal separation

In recent years a number of methods for blindly separating superimposed digitally modulated signals arriving at an antenna array have been proposed. These techniques are e cient at the up-link (mobile to base) in a mobile communication system. However, for solving the base-to-mobile beamforming problem it may be necessary to also estimate the directions-of-arrival (DOAs) of the various signal p...
