Polarization diversity in a 2x2 MIMO communication system is investigated for Alamouti and spatial multiplexing transmission schemes. Parameters such as cross polar discrimination and correlation coefficients introducing the polarization diversity are included in the channel model. Receive antenna correlation coefficients are generated from a realistic random model. The relative performance of the single and dual polarizations depends significantly on the channel characteristics. Single and dual polarization BER performances are compared for constant and distance dependent random channel parameters. It is shown that polarization diversity results better BER performance for both Alamouti and spatial multiplexing schemes compared to single polarization for the distance dependent and fully characterized channel model.

A Comparison of spatial modulation and spatial multiplexing systems in multipath fading channels Saygılı, Halil; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2013) In this thesis, multiple antenna transmission techniques like spatial multiplexing, spatial modulation and multiple active spatial modulation are compared in multipath fading channels. Maximum likelihood sequence estimation (MLSE) based on the Ungerboeck observation model is the optimal operation for intersymbol interference channels and applied on the mentioned multiple antenna transmission strategies. The performance analysis based on Monte Carlo simulations and comparison of the computational complexity ...
Fast simulation and modeling of scattering from targets in MIMO imaging systems Gül , Yunus Emre; Alatan, Lale; Department of Electrical and Electronics Engineering (2022-5-11) The forward model analysis in a multiple input multiple output (MIMO) system requires the computation of the signals received by receiver antennas when various targets are illuminated by a transmitter antenna. The full wave analysis of such systems provides accurate results with high computational cost. Fast analysis of the system can be achieved by simple models based on several approximations which limits the accuracy. In this thesis, a modeling technique that provides better accuracy compared to simple m...
Accurate multimode vibrational calculations using a B-spline basis: theory, tests and application to dioxirane and diazirinone Toffolı, Danıele; Sparta, Manuel; Christiansen, Ove (2011-01-01) The use of B-spline basis sets is explored in the context of a vibrational program for automatic potential energy surface (PES) construction and multimode anharmonic vibrational wave function calculation. Results are compared with calculations using localized Gaussians and harmonic oscillator basis functions. Potential energy surfaces are constructed in an iterative fashion using a recently developed adaptive density-guided approach. The basis set requirements for an accurate representation of the vibration...
Out-of-band radiation and CFO immunity of potential 5G multicarrier modulation schemes Üçüncü, Ali Bulut; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2015) In this study, generalized frequency division multiplexing (GFDM) and windowed cyclic preﬁx circular offset quadrature amplitude modulation (WCP-COQAM), which are candidate physical layer modulation schemes for the 5G systems, are compared to orthogonal frequency division multiplexing (OFDM) in terms of out-of-band (OOB) radiation levels and carrier frequency offset (CFO) immunity. GFDM and WCP- COQAM are shown to be superior to OFDM with respect to OOB emissions in some studies in literature. However, we c...
Multi-Point Single-Antenna Sensing Enabled by Wireless Nested Split-Ring Resonator Sensors Ozbey, Burak; ERTÜRK, VAKUR BEHÇET; Kurç, Özgür; ALTINTAŞ, AYHAN; DEMİR, Hilmi Volkan (2016-11-01) In this paper, simultaneous multi-point wireless sensing is proposed and demonstrated via multiple sensors in nested split-ring resonator (NSRR) geometry coupled to a single illuminator antenna. In this passive multi-point sensing system, each probe in the sensor array is assigned a non-overlapping spectral interval for frequency shift in response to local mechanical loading around a unique operating resonance frequency in the band of the antenna. Here, it is shown that the antenna is capable of capturing t...
