In this paper, we propose a computationally efficient algorithm with improved effective aperture for coherent angle estimation in monostatic multiple-input multiple-output (MIMO) radar. First, the direction matrix of MIMO radar is mapped into low-dimensional virtual uniform linear array (ULA). Then, an augmented data expansion obtained by exploiting Vandermonde-like structure and cross section ...

Ideal transmitting and receiving (Tx/Rx) array response is always desirable in multiple-input multiple-output (MIMO) radar. In practice, nevertheless, Tx/Rx arrays may be susceptible to unknown gain-phase errors (GPE) yield seriously decreased positioning accuracy.

The energy efficiency has become more important in MIMO wireless communication system in recent days. The antennas at each end of the communications circuit are combined to minimize errors and optimize data speed. In Multiple Input Multiple Output Time Division Duplexing (MIMO TDD), by assuming reciprocity property the downlink transmission is based on uplink channel estimation. When more uplin...

The MU-MIMO-OFDM modulation is adopted fifth-generation (5G) communication. We consider scenario where multiple mobile users share same time–frequency resources but separate...

Proportional + Integral + Derivative (PID) controllers are widely used in engineering applications such that more than half of the industrial controllers are PID controllers. There are many methods for tuning the PID parameters in the literature. In this paper an intelligent technique based on eXtended Classifier System (XCS) is presented to tune the PID controller parameters. The PID controlle...
