A multi-radio SDR technology demonstrator

Beyond multi-standard operation, SDR for consumer handsets must also aim at multi-radio operation: supporting e.g. HSPA, DVB-T, and WLAN active simultaneously on a shared hardware platform ("radio computer"). In essence, we propose an SDR operating system that provides a virtual platform for individual radios. By means of a technology demonstrator we address dynamic multi-radio operation, incl. key challenges such as unifying critical interfaces, resource management under real-time constraints, and efficiency.
