It deals with the optimization of the design and implementation of fiber optic and fiber optic transmission systems and wireless (wireless) transmission systems. Systems optimization includes research into devices that make up the systems. It also includes modeling and simulation of devices and systems themselves. One of the methods of modeling and simulation is that of finite elements. Devices research includes topics such as optoelectronics, optical amplifiers, photonics, microwave devices and applied electromagnetism. Transmission systems research encompasses topics such as error correction codes, digital modulation, digital television and digital signal processing. Systems research includes not only point-to-point systems but also multi-point systems, ie communication networks and sensor networks.
