A graduate student in the Control and Systems Engineering Department (Reem Hashim Ahmad) received a master's degree in Computers Engineering after discussing her thesis entitled "Implementation Soft Defined Radio Based Communication Network". The discussion was held on Thursday, the 16th of May 2019 in the Discussion Hall (no. 9). The examination committee consisted of:

1- Asst. Prof. Dr. Mohammed Nasser Hussein \ Chairman.

2- Asst. Prof. Dr. Ahmed Ibraheem Abdulkareem \ Member.

Wireless communications are growing exponentially, and new standards are being applied at a high pace. The development of radars is costly and time-consuming due to redundancy design of the mask cost. Moreover, as radio standards become increasingly complex, these costs are increasing. This defends a program-specific radio (SDR) approach, where one piece of flexible radios is reused for different applications and standards, downloadable and under program control. As a result, this research focuses on the implementation of a digital 16QAM SDR transmitter and receiver system based on IEEE 802.11.a. The research provides a design methodology consisting of three phases (or goals). In the first phase, 16 QAM transmitters and receivers were implemented using 16 quadrature formation techniques. The second stage was the design of a random bit generator using single-dimensional chaotic schemes (logistic map) by converting the equation to the system generator design. The third phase was to verify the performance of the proposed system by observing the bit error rate using the Adaptive White Gaussian Noise (AWGN) channel, changing the signal-to-noise ratio, and the use of 1 W of power. The system was implemented using MATLAB / Simulink 2011a and the system generator. The simulation results show that the proposed transceiver and receiver system has better performance based on AWGN channel and values of E_b ranged between 0 and 10 dB. For the system, the BER was improved to be between 10-2 and 10-3. However, the transceiver and receiver system provided better performance than the theoretical result for 1000 seconds. On this occasion, we congratulate the student (Reem Hashim Ahmed) and wish her all the success.
