Full-duplex communications systems that transmit and receive simultaneously suffer self-interference due to the mixing of transmitted signal weaker received at same node. The problem becomes compounded in Multi-Input Multi-Output (MIMO) systems, where considerable overhead is dedicated training. In this article, we discuss using blind source separation techniques, namely Independent Component A...
We quantify cell-wide mean throughputs of single-input-single-output (SISO) and multiple-inputmultiple-output (MIMO)-based cellular systems which employ multi-user diversity (MuD). Our study considers several practical and useful system-level design dimensions, including: number of transmit/receive antennas; antenna-pattern (omni-directional or sectorized); degree of error-protection (Shannon c...
اغلب پروسس هایی که در صنایع و به خصوص صنایع شیمیایی وجود دارند ورودی و خروجی های متعددی دارند. کنترل این پروسس ها که به نام : mimo (multiple input-multiple - output) معروفند، به سادگی کنترل سیستم های تک ورودی و تک خروجی : siso (single input single output) نمی باشد. زیرا سیستم های mimo تداخلی بوده و استفاده از حلقه های متعدد به فرم معمول در اغلب موارد پاسخ های مناسبی بوجود نخواهد آورد. به همین د...

Human standing balance is a complex of systems, like the muscles, nervous system and sensory systems, interacting with each other in a closed loop to maintain upright stance. With age, disease and medication use these systems deteriorate, which could result in impaired balance. In this paper, it is demonstrated that multi-input-multi-output closed loop system identification techniques (MIMO-CLS...
The use of multi-user multiple-input multiple-output (MU-MIMO) transmission is an attractive strategy to increase spectral efficiency in wireless systems such as 3GPP Long-Term Evolution (LTE) and LTE-Advanced. In this work, we investigate beamforming and scheduling strategies in the downlink of limited feedback MU-MIMO systems. Modeling transmission under orthogonal frequency-division multiple...
In this paper we propose a new approach for the modelling of the multi-variable systems (MIMO) on the Reproducing Kernel Hilbert Space (RKHS). The proposed approach considers the MIMO system as a set of MISO processes modelled in RKHS space. We propose also a comparative study of three identification kernel methods of nonlinear systems modelled in Reproducing Kernel Hilbert Space (RKHS), where ...
One of the options to mitigate fading effects in mobile communication is adaptive transmitter gain. This paper proposes a simple technique to eliminate the effects of fading in different multi antenna set-ups by varying the transmitter gain. The multi antenna set-ups considered in this paper include Single input-single output (SISO), Single input-multi output (SIMO), Multi input-single output (...
Communication technologies, in particular fifth-generation (5G) mobile phones, are currently developing around the world. Massive multi-input-multi-output (MIMO) systems usually used this type of communication network so that a large number users able to connect and use its services. MIMO good solution for 5G networks leveraging antennas improve performance. To increase output power networks, p...
