Owing to their low power consumption and cost, employing 1-bit analog-to-digital converters (ADC) in massive multiple-input multiple-output (MIMO) systems has attracted significant attention, which resulted in such systems to be examined widely in the recent literature. In our previous studies, benefits of temporal oversampling in 1-bit quantized uplink massive MIMO systems is investigated by employing a high complexity zero-forcing (ZF) detector. In this study, we propose a sequential linear receiver as an alternative to the existing ZF receiver for the temporal oversampling case in literature. The complexity of the proposed receiver for temporally oversampled uplink massive MIMO with 1-bit ADC increases linearly with block length while the complexity of the existing ZF receiver grows with the cube of block length. Furthermore, significant reduction for the delay in the estimation of the transmitted data symbols is achieved with the proposed receiver.

SYNTHESIS OF REGULATORY CONTROL-STRUCTURES FOR A STYRENE PLANT TURKAY, M; GURKAN, T; OZGEN, C (1993-05-01) Mathematical modelling and simulation of a styrene plant was made for the synthesis of a regulatory control structure for the purpose of replacing the existing one. The structural model was constructed considering the differential and algebraic relations describing the process. Utilizing the structural model, alternative feasible control structures were determined by integer linear programming (ILP) techniques developed in this study. The ILP formulations developed were proved to be very efficient in genera...
Multi-Objective Optimization of the DC-DC Stage of a Module-Integrated Inverter Based on an Efficiency Usage Model Mirjafari, Mehran; Balog, Robert S.; Turan, Raşit (2013-06-21) as photovoltaic (PV) energy continues to gain market penetration due to the lower cost of photovoltaic (PV) modules, attention is shifting to the balance-of-system. In this paper, a new efficiency evaluation technique based on a usage model synthesized from high temporal operational data of a PV module is investigated along with a multi-objective design optimization of the DC-DC stage of a Module-Integrated Inverter. The analysis shows that the technique provides more accurate results then the California En...
Pseudo-random quantization based detection in one-bit massive MIMO systems Yılmaz, Gökhan; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2023-1-18) Analog-to-digital converter (ADC) units are one of the most power-hungry devices in the radio-frequency (RF) chains of massive multiple-input multiple-output (MIMO) systems. Therefore, utilizing low-resolution ADCs in uplink massive MIMO systems is a practical solution to decrease power consumption. However, when high modulation orders are employed for high-rate communication, the achievable rate saturates after a finite SNR value due to the stochastic resonance (SR) phenomenon. This thesis proposes a novel...
Current control of single-phase VSC systems with inductor saturation using inverse dynamic model-based compensation Ozkan, Ziya; Hava, Ahmet Masum (Institute of Electrical and Electronics Engineers (IEEE), 2019-12-01) In voltage-source converter (VSC) systems, utilization of filter inductors with deep saturation characteristics is often advantageous due to the improved size, cost, and efficiency. However, with the use of conventional current regulation (CCR) methods, the inductor saturation results in significant dynamic performance loss and poor steady-state current waveform quality. This paper proposes the inverse dynamic model (IDM)-based compensation method to overcome these performance issues. The method converts th...
Gauge covariance and spin-current conservation in the gauge-field formulation of systems with spin–orbit coupling Shikakhwa, M S; Turgut, Sadi; Pak, N K (IOP Publishing, 2012-2-23) The question of gauge covariance in the non-Abelian gauge-field formulation of two space-dimensional systems with spin-orbit coupling relevant to spintronics is investigated. Although these are generally gauge-fixed models, it is found that for the class of gauge fields that are spacetime independent and satisfy a U(1) algebra, thus having a vanishing field strength, there is a residual gauge freedom in the Hamiltonian. The gauge transformations assume the form of a space-dependent rotation of the transform...
