Mimo Communication System At A Glance

چکیده

--Multiple Input Multiple Output (MIMO) communication systems are an important part of modern wireless communication standards. MIMO communication system uses multiple antennas at both transmitting and receiving ends of a communication system. Their use makes it possible to achieve higher capacity of the channel as well as increased data rates order of magnitudes than the conventional Single Input Single Output (SISO) communication systems. This paper presents an overview of a MIMO communication system. Firstly it discusses ergodic and the outage capacity for both schemes when Channel State Information is known and not known at the transmitter of a MIMO channel then it discusses space-time codes for maximization of diversity and hence improving the robustness of the communication link and the most commonly used detection techniques used to extract the correct information from the received signal reducing the Bit Error Rates (BER) to acceptable levels.

Identification and Control of MIMO Systems with State Time Delay (Short Communication)

Time-delay identification is one of the most important parameters in designing controllers. In the cases where the number of inputs and outputs in a system are more than one, this identification is of great concern. In this paper, a novel autocorrelation-based scheme for the state variable time-delay identification for multi-input multi-output (MIMO) system has been presented. This method is ba...

Performance of Target Detection in Phased-MIMO Radars

In this paper, the problem of target detection in phased-MIMO radars is considered and target detection performance of phased-MIMO radars is compared with MIMO and phased-array radars. Phased-MIMO radars combine advantages of the MIMO and phased-array radars. In these radars, the transmit array will be partitioned into a number of subarrays that are allowed to overlap and each subarray transmit...

Adaptive Neural Network Method for Consensus Tracking of High-Order Mimo Nonlinear Multi-Agent Systems

This paper is concerned with the consensus tracking problem of high order MIMO nonlinear multi-agent systems. The agents must follow a leader node in presence of unknown dynamics and uncertain external disturbances. The communication network topology of agents is assumed to be a fixed undirected graph. A distributed adaptive control method is proposed to solve the consensus problem utilizing re...
