The Department of Communications Engineering at the University of Technology awarded a master's degree to student Jaafar Ali Jaafar for his thesis

“Evaluating the performance of multiple-input, multiple-output technology on an optical network.”

The thesis aims to design a free-space communication system with a high data transfer rate through the use of different types of advanced modulation techniques under different climatic conditions

. In addition, applying multiple input, multiple output technology to mitigate these effects. The message also aimed to increase the capacity of the system by using WDM technology with different spacing distances between channels and observing the effect of changing that distance on the system.

:Most notable results
The use of multiple inputs and multiple outputs technology led to improving the system by reducing the effect of signal drop due to weather and increasing the transmission range by 49.3%, 78.6%, and 108% for the 2x2, 4x4, and 8x8 technologies, respectively, under clear weather conditions. This percentage decreased to 12.33%, 18.5%, and 24.6% under heavy dust conditions.
