Problem statement: In the real world most of the controlled processes in industries are Multi-Input Multi-Output (MIMO) in nature.They have more than a single controlled variable that should be manipulated in order to achieve the desired control performance. Approach: Control of non linear Multi Input Multi Output processes, it is a difficult task because of the non stationary behaviour, substa...

This paper deals with the problem of robust adaptive controller design for a class of Multi-Input and Multi-Output (MIMO) time delay uncertain systems based on backstepping method and fuzzy logical system (FLS). This problem aims at designing robust adaptive controller for all parameter uncertainties and time delay of MIMO system with backstepping method. This studied system consists of some su...

Space-time block codes (STBC) and spatial multiplexing (SM) are promising techniques that effectively exploit multipleinput multiple-output (MIMO) transmission to achieve more reliable communication and a higher multiplexing rate, respectively. In this paper, we study a practical design for hybrid scheme with multi-input multi-output orthogonal frequency division multiplexing (MIMOOFDM) systems...

Polynomial singular value decomposition (PSVD) plays a very important role in broadband multiple-input multiple-output (MIMO) systems. One of its applications lies in the decoupling of MIMO convolutive mixing channel matrix in order to recover the transmitted signals corrupted by the channel interference (CI) at the receiver. In this paper, a novel algorithm, known as multiple shift second orde...

The capacity performance of multi-user multiple input multiple output (MIMO) in a cellular system is of a great interest. This paper presents a comparative study on the transmit power control (TPC) schemes for uplink multi-user MIMO systems. Two kinds of TPC schemes, namely, zero-outage TPC and minimum interference TPC, are considered. The capacities of both schemes are theoretically analyzed a...

Sensor networks require robust and efficient communication protocols to maximise the network lifetime. Radio irregularity, channel fading and interference results in larger energy consumption and latency for packet transmission over wireless channel. Cooperative multi-input multi-output (MIMO) schemes can combat the fading effects in wireless sensor network (WSN) and can significantly improve t...

There are three basic concepts behind the standard feedback optimization setup: the notion of a multi-input, multi-output (MIMO) linear time-invariant (LTI) finite order system, the notion of an internally stable feedback interconnection of two MIMO LTI systems, and the notion of a system norm. In addition, there is a concept of well-posedness of the resulting optimization problem, which has to...

Multi Input Multi Output (MIMO) communication is a proven technique to increase the throughput, diversity gain and increase the energy gain by reducing the energy consumption of the wireless network. Space time diversity used in MIMO systems is a technique to mitigate multipath fading. The same information is transmitted over multiple channels that fade independently. So, space time diversity i...

As a generalization of orthogonal frequency-division multiplexing (OFDM) systems, multi-input multi-output (MIMO) OFDM systems are very sensitive to carrier frequency offset (CFO). This paper proposes a blind CFO estimation method based on power spectrum analysis, which has high bandwidth efficiency and is much less complex. This method can be used to estimate the residual CFO, which is less th...
