Massive MIMO and non-orthogonal multiple access (NOMA) are key technologies for next generation wireless systems due to their distinct advantages. We previously proposed a general framework on unification of code-domain NOMA and joint spatial division and multiplexing (JSDM) which is a spatial user-grouping based hybrid beamforming method for massive MIMO. In this paper, we propose a constrained analog beam-former design for JSDM based systems. Moreover, we propose joint group processing for the digital beamformer in order to reduce the interference introduced by constrained beamformers. We provide a comprehensive performance evaluation for different operational modes of JSDM with code-domain NOMA when constrained analog beamformers are utilized.

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 noma map receiver for wideband mimo channels Şatana, Hasan Aykut; Güvensen, Gökhan Muzaffer; Department of Electrical and Electronics Engineering (2020-10) Multiple input and multiple output (MIMO) technology and non-orthogonal multiple access (NOMA) are two important concepts for the next generation communication systems since they bring many advantages over conventional orthogonal systems. While there are numerous research over MIMO and power domain NOMA integration, the combination of MIMO and practical code domain NOMA schemes has not been investigated much in the literature, which is the subject of this thesis. In this study, we propose a generic maximum ...
A Random Access Scheme for Large Scale 5G/IoT Applications Balevi, Eren; Gitlin, Richard D. (2018-01-01) The integration of slotted Aloha with power domain non-orthogonal multiple access (NOMA), dubbed slotted Aloha-NOMA (SAN) can emerge as an appealing MAC protocol to be used for Internet-of-Things (IoT) applications over 5G networks. In this paper, SAN is discussed, and its performance is evaluated in detail. The simulation results demonstrate that the maximum normalized throughput can be increased from 0.37, which is the case for slotted Aloha, to 1 by means of SAN. Specifically, this full throughput effici...
A novel architecture proposal for multi-access management in IP-based future wireless networks Altundaş, Süleyman; Buyurman, Baykal; Department of Electrical and Electronics Engineering (2003) As the wireless networking technologies advance rapidly, providing mobile users with roaming freely in heterogeneous wireless access domains, the need for multi access arises. This thesis proposes a novel Mobile Multi-Access Management Architecture (MMA-IP) for IP-based future wireless networks. The thesis includes a proposal for a PhD study towards establishing such an architecture. MMA-IP enables mobile users to utilize multiple access domains synchronously and to switch seamlessly between different acces...
A NOVEL FLEXIBLE ON-CHIP SWITCH ARCHITECTURE FOR RECONFIGURABLE HARDWARE ACCELERATORS Yazıcı, Fatih; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2021-8-13) This thesis work proposes ReFlex Switch, a novel, scalable on-chip packet switch architecture, that is designed to interconnect heterogeneous IP cores at high speeds. One target application for ReFlex switch is hardware accelerated cloud computing where the cloud servers feature FPGA cards with reconfigurable regions to implement accelerators demanded by the users. In this setting, the increasing data rates call for line-speed operation of the on-chip switch to maintain scalability. The first requirement o...
