The main objective of this work was the development of the directional modulation (DM) technique, which is a promising keyless physical layer security means for securing wireless communication in free space. It is realized, from a summary of the state-of-the-art OM systems, that although the OM concept appears to be a competitive candidate to enhance the secrecy performance of the next generation of wireless communication, it suffers various fundamental problems, which makes the OM research carried out in an unsystematic and inefficient manner. In order to integrate the previous scattered OM efforts and further pave the path for its applications, in this thesis a theoretical OM framework has been established and some key concepts and OM architectures have been validated via well designed experiments.
