It is expected that multiple radio access standards and systems will coexist in the same environment beyond 3G. The superior re-configurability and re-programmability of software-defined radio (SDR) had made itself become the most promising technology to realize such a flexible radio system. Several research projects have involved in the development of SDR systems, but their efforts mainly focus on hardware design. A software framework that allows users, manufactories or operators to insert, remove, update and configure protocols, applications and hardware modules is also an essential part of a SDR system. Unfortunately, current commercial operating systems (OS) lack of fully supports of SDR features. In this paper, the impacts of SDR to the OS and the extension of the OS for a SDR system are investigated. Moreover, the design and implementation of a software framework based on a commercial on-the-shelf (COTS) OS are also presented.
