In this paper, we study the performance of an antenna switching (AS) system in a multipath Rayleigh fading channel in comparison to an Alamouti coded system. We propose a minimum mean-squared error based iterative equalizer for the multi-antenna system. In the proposed receiver, MMSE equalization and channel decoding are jointly carried out at each iteration by using the a priori probabilities from previous iterations. It is observed that Alamouti based scheme performs better when the channel state information is perfect. It turns out that the antenna switching based system performs significantly better in the case of imperfect channel state information.

Yıldırım, Recep Ali; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2010)
In this thesis, we study the performance of an antenna switching (AS) system in comparison to an Alamouti coded system. We analyze the outage probabilities and propose minimum mean-squared error based iterative equalizers for both systems. We see from the outage probability analysis of both systems that the AS system may achieve the same diversity order of the Alamouti coded scheme contingent on the transmission rate and constellation size. In the proposed receiver, MMSE equalization and channel decoding ar...
Three Dimensional Microfabricated Broadband Patch and Multifunction Reconfigurable Antennae for 60 GHz Applications
Hunerli, H. V.; Mopidevi, H.; Cagatay, E.; Imbert, M.; Romeu, J.; Jofre, L.; Cetiner, B. A.; BIYIKLI, NECMİ (2015-05-17)
In this paper we present two antenna designs capable of covering the IEEE 802.11ad (WiGig) frequency band (57-66 GHz and 59-66 GHz respectively). The work below reports the design, microfabrication and characterization of a broadband patch antenna along with the design and microfabrication of multifunction reconfigurable antenna (MRA) in its static form excluding active switching. The first design is a patch antenna where the energy is coupled with a conductor-backed (CB) coplanar waveguide (CPW)-fed loop s...
Maximal Ratio Combining with Energy Harvesting Multi-Antenna Receivers
Uctu, Goksel; Yüksel Turgut, Ayşe Melda (2015-01-01)
In this study, we consider a wireless communication system in a point-to-point fading channel with additive white Gaussian noise. The relationship between consumed energy on sampling and decoding processes at the receiver side is a known fact. Accordingly, a receiver model that has two antennas combined with maximal ratio combining technique is considered and energy consumptions of such a system on sampling and decoding processes are evaluated. Total energy consumptions of both systems are compared under va...
Modified neural multiple source tracking algorithm in the presence of mutual coupling
Caylar, Selcuk; Leblebicioğlu, Mehmet Kemal; Dural, Guelbin (2007-06-15)
In smart antenna systems, mutual coupling between elements can significantly degrade the processing algorithms [1]. In this paper mutual coupling effects on Modified Neural Multiple Source Tracking Algorithm (MN-MUST) has been studied. MN-MUST algorithm applied to the Uniform Circular Array (UCA) geometry for the first time. The validity of MN-MUST algorithm in the presence of mutual coupling has been proved for both Uniform Linear Array (ULA) and UCA. Simulation results of MN-MUST algorithm are provided fo...

Güvensen, Gökhan Muzaffer; Tanık, Yalçın; Yılmaz, Ali Özgür (2010-11-03)
In this paper, we evaluate the Cramer-Rao bounds (CRB) for the estimation of the carrier frequency offset (CFO) for general QAM modulations with no knowledge of the transmitted sequence (blind operation) in frequency hopping (FH) based short burst mode mobile radios. We investigate the blind CFO estimation problem in FH based mobile system that uses multiple short narrowband bursts in different frequency channels for the transmission of one packet. Joint blind channel and CFO estimation over multiple freque...
