A research team from the College of Engineering at Diyala University, which included the lecturer Marwa Muhammad Jawad, and Lecturer Hira Rahim Hatim, and Assistant Lecturer Qasim Muhammad managed to publish a scientific study entitled (Performance Enhancement of Audio Transmission Based on LMMSE Method) in an Indonesian journal which is located within SCOPUS database: (Indonesian Journal of Electrical Engineering and Computer Science)

The study aimed at suggesting a system that is based on a special multiplexing technique and linear minimum mean square error detection method by the assistance of hamming code as well as the interleaving techniques for a better-enhanced performance of the audio transmission.

Moreover, the study included a comparison between the two systems for different antenna configurations with the presence of two types of modulation: binary phase shift key and quadrature phase-shift key.
