Active Projects

Interference Management in Cognitive Radio Networks

This project includes reducing interference in military communications utilizing efficient spectrum allocation for all terminals. In addition, the projects aims to support different location and network topologies without spectrum planning in military communications. Flexibility to use in countries' borders or conflict zones is aimed for designing next generation  communication systems that can be configured dynamically.

Efficient IoT System Design Through Energy Harvesting

Powering the IoT devices is an important issue in the 5G and beyond. Conventional batteries won’t work in the IoT applicaitons because of their various shapes and sizes and low power requirements. Therefore, power sources for IoT devices will need several key features of their own like: small/thin size and flexible shape and wireless connectivity which ables them to charge a device on the go, easy to use anywhere. A promising approach of power source alternatives for the IoT is harvesting energy from radio frequencies.

Optimization of a mobile network based on most used sites / routes

Using the signaling information which contains the handover attempts and successes between the spurge and destination cells, it is possible to form a pattern of sites and cells in a matrix, that indicate the typical route that mobility, service and capacity needs to be sured for the smooth operation of the mobile network. This is valid for all the technologies and also for voice and data, even though voice will benefit the most from this type of optimization. Using machine learning and forecasting, it is possible to predict the traffic that can be carried by new sites that can be introduced in the network as well as the amount of traffic lost due to the loss of a site/ radio/ cell.

LTE eNodeB Performance Measurement, Software Development of Self-Configurable Networks

LTE eNodeB Performance Measurement, Software Development of Self-Configurable Networks: The role of handover parameters in improving the energy efficiency of cellular networks is analyzed, and the negative effects of handover failure (HOF) and ping-pong (PP) rate are investigated. The network performance of the new algorithm is explored in terms of real vehicular traffic data and state-of-the-art specifications of eNodeBs.

High-resolution time-frequency distributions on the application of spread-spectrum communications and dissimilarity measures and retrieval on time-frequency distributions

High-resolution time-frequency representations are developed and applied to various communication applications. Moreover, fractional Fourier domain adaptive filter has been designed and original results in the discrete form of the transform are obtained. Signal retrieval and classification problem is also investigated by time-frequency signal processing.

Detection and Parameter Extraction of Low Probability of Intercept Radar Waveforms by Time-Frequency Signal Processing

Conventional pulsed radar systems are easily detected by advanced electronic support systems and radar warning receivers due to their high-powered transmissions. As the use of low probability of intercept (LPI) radar waveforms provides significant advantages in radar systems, we investigate LPI radar waveform detection and parameter extraction in this project. The proposed novel analysis techniques are implemented on the FPGA.
