In frame based communication systems, blind identification of frame length and offset from limited number of observations has an important affect on the performance of blind channel identification and equalization algorithms. In [1], for guard interval transmission schemes, a novel blind frame length and offset estimation method is proposed. In this paper, the performance of methods proposed in [1] for fixed frame length transmission are studied.

Identification of inertial sensor error parameters
Altınöz, Bağış; Leblebicioğlu, Mehmet Kemal; Department of Electrical and Electronics Engineering (2015)
Inertial sensors (gyroscopes and accelerometers) that are used in navigation systems have distinct error characteristics such as bias, scale factor, random walk, etc. Calibration and characterization tests are done with 2 or 3 axes rate tables in order to identify these errors. It is possible to utilize error characteristics of these devices, and the navigation accuracy is directly dependent on the accuracy of this identification process. In this thesis, inertial sensor error parameters are identified by a ...
Effect of Visual Context Information for Super Resolution Problems
Akar, Gözde; Aykut, Ekin; Cengiz, Baran; Bocek, Kadircan (2019-04-26)
In this study, the effect of visual context information to the performance of learning-based techniques for the super resolution problem is analyzed. Beside the interpretation of the experimental results in detail, its theoretical reasoning is also achieved in the paper. For the experiments, two different visual datasets composed of natural and remote sensing scenes are utilized. From the experimental results, we observe that keeping visual context information in the course of parameter learning for convolu...
Effects of experimental parameters in monitoring the hydration of cement mortars by ultrasonic testing
Keskin, Ö. Kasap; Yaman, İsmail Özgür; Tokyay, Mustafa (2012-12-01)
In ultrasonic pulse velocity testing, frequency and the travel path length are important parameters that determine the attenuation rate and the influence of near-field effect. Higher frequencies and longer distances result in higher attenuation. On the other hand, smaller path lengths are not desirable due to near-field effect. This study investigated the effect of transducer frequency and the length of path used to determine ultrasonic wave velocity in monitoring the hydration process of fresh cement morta...
Classification in Frequency Domain of EEG Signals of Motor Imagery for Brain Computer Interfaces
Halıcı, Uğur (2009-05-22)
In this study the classification of the EEG signals recorded during motor imagery for curser movement in brain computer interfaces is examined, in which the feature vectors obtained in frequency domain is used and then the linear transformations are applied for reducing the size of the feature vectors.
Effects of surface reflectance on local second order shape estimation in dynamic scenes.
Dövencioğlu, Nahide Dicle; Ben-Shahar, O; Doerschner, K (2015-10-01)
In dynamic scenes, relative motion between the object, the observer, and/or the environment projects as dynamic visual information onto the retina (optic flow) that facilitates 3D shape perception. When the object is diffusely reflective, e.g. a matte painted surface, this optic flow is directly linked to object shape, a property found at the foundations of most traditional shape-from-motion (SfM) schemes. When the object is specular, the corresponding specular flow is related to shape curvature, a regime c...
