This thesis investigates efficient interference-aware beamformer design for mm-wave massive multiple-input and multiple-output (MIMO) systems. Furthermore, adaptation of code-domain non-orthogonal multiple access (NOMA) to mm-wave massive MIMO is studied. The first part of the thesis concentrates on interference-aware pre-beamformer (analog beamformer) design for joint spatial division and multiplexing (JSDM) which is a user-grouping based two-stage beamforming method. Single-carrier frequency domain equalization (SC-FDE) is employed in uplink wideband channels. First, unconstrained statistical analog beamformer of each group, namely, generalized eigenbeamformer (GEB) which has strong interference suppression capability is designed. Then, constant-modulus constrained approximations of unconstrained beamformer are obtained by utilizing alternating minimization algorithms. Moreover, a dynamic subarray algorithm is proposed where the connections between radio frequency (RF) chains and antennas are dynamically changed. Minimum mean square error (MMSE) criterion based iterative block decision feedback equalization (IB-DFE) method, which takes the residual interference in reduced dimension into account, is proposed for intra-group processing. Simulation results verify the superiority of the proposed interference-aware constrained design over existing approaches in terms of beampattern, spectral efficiency, outage capacity, bit-error rate (BER) and channel estimation accuracy. The second part of the thesis is devoted to the development of a novel wideband signal model in beamspace for code-domain NOMA with SC-FDE transmission in JSDM framework. Based on this signal model, a code-beamspace IB-DFE receiver is proposed for joint equalization and multiuser detection, and it is shown that code-domain NOMA is beneficial, especially for mm-wave massive MIMO systems with limited number of RF chains and spatial correlation.

An experimental study for simulation based assessment of information system design performance Ayyildiz, Bulent; Akman, Ibrahim; Arifoğlu, Ali (2007-07-04) This paper presents an experimental study for evaluating the decision support value of queueing network (QN) based simulation models for information system design performance. For illustration, queueing network simulation models have been extracted corressponding to three annotated design alternatives of a selected case study. The design alternatives are produced using logical requirements of the selected system. The performance of each alternative is then predicted using quantifiable parameters considering...
An Efficient Interference-Aware Constrained Massive MIMO Beamforming for mm-Wave JSDM Bayraktar, Murat; Güvensen, Gökhan Muzaffer (2021-01-01) Low-complexity beamformer design with practical constraints is an attractive research area for hybrid analog/digital systems in mm-wave massive multiple-input multiple-output (MIMO). This paper investigates interference-aware pre-beamformer (analog beamformer) design for joint spatial division and multiplexing (JSDM) which is a user-grouping based two-stage beamforming method. Single-carrier frequency domain equalization (SC-FDE) is employed in uplink frequency-selective channels. First, unconstrained slowl...
A Nonlinear Detector for Uplink SC-FDE mm-Wave Hybrid Massive MIMO under Hardware Impairments Salman, Murat Babek; Güvensen, Gökhan Muzaffer (2021-06-01) In this paper, we propose a detector structure for fully connected hybrid massive MIMO systems with transceiver impairments at user equipments. In literature, memoryless compensation of nonlinear effects at the receiver side is recently proposed for systems employing frequency domain equalization. However, in these studies, the system model is restricted to be symbol sampled, where pulse shaping and fractional delays in channel impulse response (CIR) are not taken into consideration. However, memory effects...
A Reduced complexity hybrid precoding architecture and user grouping algorithms for downlink wideband massive MIMO channels Kilcioğlu, Emre; Güvensen, Gökhan Muzaffer; Department of Electrical and Electronics Engineering (2019) In this thesis, an efficient hybrid precoding architecture is proposed for single-carrier (SC) downlink wideband spatially correlated massive multiple-input multiple-output (MIMO) channels. The design of two-stage beamformers is realized by using a virtual sectorization via second-order channel statistics based user grouping. The novel feature of the proposed architecture is that the effect of both inter-group-interference (due to non-orthogonality of virtual angular sectors) and the inter-symbol-interferen...
Applied supervisory control for a flexible manufacturing system Moor, Thomas; Schmidt, Klaus Verner; Perk, Sebastian (2010-12-01) This paper presents a case study in the design and implementation of a discrete event system (DES) of real-world complexity. Our DES plant is a flexible manufacturing system (FMS) laboratory model that consists of 29 interacting components and is controlled via 107 digital signals. Regarding controller design, we apply a hierarchical and decentralised synthesis method from earlier work in order to achieve nonblocking and safe closed-loop behaviour. Regarding implementation, we discuss how digital signals tr...
