Spatial multiplexing advantages of Massive MIMO systems which have an important part of the future generation cellular communication systems come to the forefront thanks to large number of antennas at base station. Base ...

In the recent years, development of wireless communication devices lead to high demand of wireless communication system traffic and this demand is steadily rising day by day. At the same time, energy consumption problem ...

Ionosphere has a great importance on radio wave propagation. Thanks to the high electron density it contains, it forms reflective ionosphere layers. Ionosphere enables High Frequency (HF) Communication by reflecting radio ...

Learning an object category from only a few samples is generally not adequate for correct classification. One needs many training samples to obtain a classifier that generalizes well and that has sufficient success rates. ...

Multicarrier systems are preferred today due to their robustness to the multipath effects and using fast fourier transform(FFT) easily to feasible and more efficient in many communication systems. Orthogonal Frequency ...

In the scope of this study, attitude determination using GNSS systems is discussed. The concept of attitude is defined together with transformations between coordinate systems to express the position of an aerial vehicle. ...

Edge detection algorithms are to be among the most common tools for digital image processing procedures. The success of these algorithms influences directly the performance of the applications based on image processing in ...

One of the mostly used band for long range communication is High Frequency (HF) band. Radio waves in the HF band range (3 − 30 MHz) are reflected from ionosphere which is one of the layers of atmosphere. So, a communication ...

In this thesis, indoor localization problem is investigated using received signal strength indicator and acceleration measurements. After localization with received signal strength and accelerometer separately, indoor ...

When determining the method to be used in shielding effectiveness measurements, the size and shape of the screen material together with the cost, applicability, time consumption and frequency range characteristics to be ...
