This paper is a brief overview over the development of software-de?ned or recon?gurable radio systems. The need for software-de?ned radios is underlined and the most important notions used for such recon?gurable transceivers are thoroughly de?ned. The role of standards in radio development is emphasized and the usage of transmission mode parameters in the construction of software-de?ned radios is described. The software communications architecture is introduced as an example for a framework that allows an object-oriented development of software-de?ned radios. Cognitive radios are introduced as the next step in radio systems’ evolution. The need for cognitive radios is exempli?ed by a comparison of present and advanced spectrum management strategies.
