Abstract :
Radio configuration (R-CFG) files for software defined radio (SDR) devices can he downloaded over the air, allowing these devices to support multi-mode functionality using a single transceiver. The drawback of this is that the wireless link is constrained and downloading the entire R-CFG could take some time. In an effort to achieve efficiency, this paper presents a new algorithm for differential download, referred to as light differential download algorithm (LDDA). The LDDA is the first differential download algorithm specifically designed for SDR devices. It presents several new features that make not only R-CFG differential download a possibility, but also allows the update of any software by differential download. Experiments using Java 2 Micro Edition are performed to demonstrate the feasibility and superior performance of the LDDA when compared with other approaches.
