dc.description.abstractIn this thesis, Directional Modulation (DM) as a technique to enhance security in the physical layer (PHY) for wireless communication systems is discussed, and a multiple-input, multiple-output (MIMO) DM radio is designed using GNU Radio software. A DM processing block for a MIMO system with two transmit and two receive antennas based on the knowledge of the channel state information (CSI) is implemented and tested in GNU Radio. An attempt to demonstrate a physical DM communication system using GNU Radio and universal software radio peripheral (USRP) devices is described, the problems faced during the experimental setup are included, and the reasons it was not finally completed for real testing are explained. Bit Error Rate (BER) calculations are presented by simulating a MIMO DM QPSK communication system in the GNU Radio Companion (GRC) environment using the implemented DM block. The simulation results illustrate the capability of the MIMO DM system to achieve small BER at an intended receiver and large BER for potential eavesdroppers.en_US
