A soft radio architecture for reconfigurable platforms

While many soft/software radio architectures have been suggested and implem ented, there remains a lack of a formal design methodology that can be used to design and implement these radios. This article presents a unified arch itecture for the design of soft radios on a reconfigurable platform called the layered radio architecture. The layered architecture makes it possible to incorporate all of the features of a software radio while minimizing com plexity issues. The layered architecture also enables a methodology for inc orporating changes and updates into the system. An example implementation o f the layered architecture on actual hardware is presented in the article.
