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...

The increasing interest in MIMO (Multiple-Input Multiple-Output) systems has given rise to a proliflc research activity in recent years. Both theoretical and practical issues have been studied. However, so far few MIMO testbeds or prototypes have been built for DVB-T or future standards. In this paper, a novel 2 x 2 MIMO testbed speciflcally designed for evaluating the performances of a DVB-T2 ...

This paper presents an approach that how to locate and to detect obstacle or hurdles or the human being or any living being, using synthetic aperture radar (SAR). The paper consist of the acknowledgement of idea how to trace the any moving object on earth level or above the earth level bye using GMTI(Ground Moving Target Indicator) or synthetic aperture radar SAR. It is demonstrated that SAR pr...

Multiple Input Multiple Output (MIMO) represents a highly promising technique for 4G communication networks as it uses multiple antennas at the transmitter and receiver to improve the reliability of transmissions and to provide a high data rate. This paper introduces an adjustable scheduling algorithm for multi-user MIMO systems that can provide an advantageous trade-off solution between throug...

The Multiple–antenna technique called MIMO (Multiple-Input-Multiple-Output) constitutes a key technology for modern and future wireless communications, which trade– off superior error performance and higher data rates for increased system complexity and cost. As an extension to the classical MIMO schemes, a novel technique called Spatial Modulation(SM) can even enhance the capability of MIMO sy...

Single-input single-output (SISO), systems with zeros interlacing poles (ZIP) have been extensively studied in the literature and received interest widely. However, ZIP property for multiple-input multiple-output (MIMO), has not pursued sufficiently. In this article, we pursue MIMO link to strict passivity. For class of that admit a symmetric state-space realization, which SISO case is equivale...

This paper presents the implementation and mapping exploration of the physical layer algorithms in a single input single output (SISO) and multiple input multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) systems on a commercial heterogeneous multiprocessor hardware platform. We focus our investigations on the algorithms for implementing two computation-intensive component...

The asymptotic –in the number of antennas– theoretic capacity of a MIMO (Multiple Input Multiple Output) system is derived when considering Rice distribution entries. Assuming perfect knowledge of the channel at the receiver, analytical expressions of the capacity are derived in the case of perfect and partial (based on the mean and limiting eigenvalue distribution of the mean) knowledge at the...

This paper proposes per-tone equalization methods for single carrier block transmission with cyclic prefix (SC-CP) systems. Minimum mean-square-error (MMSE) based optimum weights of the per-tone equalizers are derived for SISO (single-input single-output), SIMO (single-input multipleoutput), and MIMO (multiple-input multiple-output) SC-CP systems. Unlike conventional frequency domain equalizati...

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...
