In this paper, an alternative method is proposed instead of the ones using semi-definite programming (SDP) tools in precoder and decoder design to solve max-min fairness (MMF) problem in the multiuser downlink multi-input-multi-output (MIMO) communication systems for common and private information transmission. This is a Hybrid method which is the combination of the two solving total signal-interference plus noise ratio (SINR) maximization (Total-SINR Max) and total MMSE (Joint-TMSE) problems and it is very advantageous than algorithms using SDP. The performance of Hybrid method in terms of the average bit error ratio (BER) and computation time is given in the simulation results.

An Efficient Hybrid Beamforming and Channel Acquisition for Wideband mm-Wave Massive MIMO Channels Kurt, Anıl; Güvensen, Gökhan Muzaffer (2019-01-01) In this paper, 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 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 sec...
A new electromagnetic target classification method with MUSIC algorithm Secmen, Mustafa; Sayan, Gönül (2006-01-01) This paper introduces a novel method for aspect invariant electromagnetic target recognition based on the use of multiple signal classification (MUSIC) algorithm to extract late-time resonant target features from the ultra-wideband scattered data. This method is mainly based on the usage of MUSIC spectra obtained from electromagnetic scattered data as the target features. This approach achieves very high accuracy rates even at very low signal-to-noise ratio (SNR) values although it needs scattered data for ...
A diversity and coding gain analysis for the cooperative wireless communication channel under fading using sampling property of the Q-function İşbi̇rli̇kli̇ kablosuz haberleşmede sönümlemeli̇ kanal i̇çi̇n Q-fonksi̇yonunun örnekleme özelli̇ǧi̇nden yararlanan bi̇r çeşi̇tleme ve kodlama kazanci anali̇zi̇ Aktaş, Tuǧcan; Yılmaz, Ali Özgür; AKTAŞ, EMRE (2012-07-09) This work presents approximation methods that are used to identify Bit Error Rate (BER) expressions which are frequently utilized in investigation and comparison of performance for wireless communication systems in the literature. In this group of approximation methods, some expectation integrals, which are complicated to analyze and time-consuming to evaluate through Monte Carlo simulations, are handled. For this group of integrals, by using the sampling property of the Q-function under mid- and high- Sign...
A novel electromagnetic target recognition method by MUSIC algorithm Secmen, Mustafa; Sayan, Gönül (2006-12-01) This paper introduces a novel method for aspect invariant electromagnetic target recognition based on the use of multiple signal classification (MUSIC) algorithm to extract late-time resonant target features from the ultra-wideband scattered data. This approach achieves very high accuracy rates even at very low signal-to-noise ratio (SNR) values although it needs scattered data for classifier design at only a few different aspects and makes use of the MUSIC algorithm in a simple and computationally efficien...
A Low-Complexity Graph-Based LMMSE Receiver for MIMO ISI Channels With M-QAM Modulation Sen, Pinar; Yılmaz, Ali Özgür (2017-02-01) In this paper, we propose a low complexity graph-based linear minimum mean-square-error (LMMSE) equalizer in order to remove inter-symbol and inter-stream interference in a multiple input multiple output (MIMO) communication. The proposed state space representation inflicted on the graph provides linearly increasing computational complexity with block length. In addition, owing to the Gaussian assumption used in the presented cycle-free factor graph, the complexity of the suggested equalizer structure is no...
