In this paper, a hybrid system consisting of analog and digital beamformers is proposed to reduce the hardware complexity of full digital beamforming. In analog beamforming part, specially chosen two-bit radio frequency (RF) phase shifters are used. Two-bit structure enables the conversion of the discrete optimization problem to a continuous programming form which gives faster and more efficient solution. The optimization problem is formulated as a quadratic-cost problem and is solved iteratively by exact penalty and semidefinite programming. Simulation results show that the proposed method performs with considerable efficiency and effectiveness.

HYBRID BEAMFORMING WITH TWO BIT RF PHASE SHIFTERS IN SINGLE GROUP MULTICASTING
Demir, Özlem Tuğfe; Tuncer, Temel Engin (2016-03-25)
In this paper, an efficient hybrid beamforming architecture combining analog and digital beamforming is proposed to reduce the number of radio frequency (RF) chains. It provides a good compromise between the higher degree of freedom of digital beamforming and hardware cost and complexity. In this hybrid system, two bit RF phase shifters are used as analog beamformers due to the fact that this enables the conversion of the combinatorial optimization problem to a continuous programming formulation. The overal...
Antenna Selection and Hybrid Beamforming for Simultaneous Wireless Information and Power Transfer in Multi-Group Multicasting Systems
DEMİR, ÖZLEM TUĞFE; Tuncer, Temel Engin (2016-10-01)
In this paper, low-cost alternatives to full digital beamforming, namely, antenna selection and hybrid beamforming, are proposed for simultaneous wireless information and power transfer in a multi-group multicasting scenario. The joint problem can be outlined as the design of beamformer weight vectors and power splitting ratios in order to satisfy both signal-to-interference-plus-noise - ratio and harvested power constraints at each user with minimum transmission power. We first develop an efficient algorit...
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 Compact Angular Rate Sensor System Using a Fully Decoupled Silicon-on-Glass MEMS Gyroscope
Alper, Said Emre; Temiz, Yuksel; Akın, Tayfun (Institute of Electrical and Electronics Engineers (IEEE), 2008-12-01)
This paper presents the development of a compact single-axis angular rate sensor system employing a 100-mu m-thick single-crystal silicon microelectromechanical systems gyroscope with an improved decoupling arrangement between the drive and sense modes. The improved decoupling arrangement of the gyroscope enhances the robustness of sensing frame against drive-mode oscillations and therefore minimizes mechanical crosstalk between the drive and sense modes, yielding a small bias instability. The gyroscope cor...
A General framework on adaptive hybrid beamformingand channel acquisition for wideband mm-wave massive MIMO systems
Kurt, Anıl; Güvensen, Gökhan Muzzaffer.; Department of Electrical and Electronics Engineering (2019)
In this thesis, an efficient hybrid beamforming architecture together with a novel spatio-temporal receiver processing is proposed for single-carrier (SC) mm-wave wideband massive MIMO channels in time-domain duplex (TDD) mode. The design of two-stage beamformer 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 sec...
