In this paper, we investigate the Zero-Forcing equalizer based on Fast One Sided Jacobi (ZF-FOSJ) algorithm for the Multiple Input Multiple Output Power Line Communication (MIMO PLC) systems. The proposed algorithm determines the pseudo-inverse of estimated channel matrix using only real matrix and operations free from trigonometric functions. The hardware implementation complexity is reduced c...
Multiple Input Multiple Output (MIMO) systems have been an important area for future wireless systems, as it can provide high capacity, good diversity and less interference. This technique is very attractive for wireless communication to increase data rates and system performance. A radio propagation channel is a one that gives the characteristics of MIMO systems. Different approaches have been...
Virtual multiple input multiple output (MIMO) techniques are used for energy efficient communication in wireless sensor networks. We investigate virtual MIMO for fixed and variable rates. We propose energy efficient routing based on virtual MIMO. The simulation results show that virtual MIMO based routing is more energy efficient as compared to SISO (single input single output) for larger dista...
The paper gives an overview of the multiple-input multiple-output (MIMO) systems and discusses their benefits enabling an increase in the system capacity and an increase of system reliability. The former is attained by signal multiplexing and the later by space encoding. The basic algorithms required for a proper operation of the MIMO systems, i.e. channel estimation, equalisation, optimal and ...
An effective numerical approach is developed for orthogonal waveform design for Multiple-Input Multiple-Output (MIMO) radar. The Doppler shift tolerance is considered in the design cost function. The design results indicate that the Doppler tolerance of the designed orthogonal waveforms is markedly improved. Keywords-MIMO radar; waveform design; Doppler effect;
An analysis of MIMO antenna system in the development of LTE (Long Term Evolution) terminal and the compensation of user’s induced loss is presented in this paper. MIMO wireless systems have antenna arrays at both the transmitter and receiver terminals. Multiple input multiple output (MIMO) technology has been regarded as a practical approach to achieve significant increase of wireless channel ...
In this paper, the construction and analysis of multiple input multiple output (MIMO) subnets is presented. Hierarchical Time-Extended Petri Nets (H-EPNs), allow for the generation of MIMO subnets through bottom-up synthesis techniques similar to those discussed in PN literature [3]. A simple transformation of these MIMO subnet structures into equivalent single input single output (SISO) subnet...
A multi-input and multi-output optimal controller for stochastic systems with time-varying dynamics is developed. The system to be controlled is described using a multi-input and multi-output time-varying autoregressive moving average model with multiple delays. The controller minimises a generalised minimum variance cost functional that is the sum of quadratic output tracking error variances a...
|A number of techniques have been introduced to construct fuzzy models from measured data. Most attention has been focused on multiple-input, single-output (MISO) systems. This article concentrates on the identi cation of multiple-input, multiple-output (MIMO) systems by means of product-space fuzzy clustering with adaptive distance measure (the Gustafson-Kessel algorithm). The MIMOmodel is rep...
Multiple antenna communications technologies offer significant advantages over single antenna systems. These advantages include extended range, improved reliability in fading environments and higher data throughputs. If multiple antennas are provided only at the transmitting end of a link then the system is referred to as multiple input single output (MISO). If multiple antennas are provided on...
