MULTI-RADIO SCHEDULING AND RESOURCE SHARING ON A SOFTWARE DEFINED RADIO COMPUTING PLATFORM

Beyond multi-standard operation, SDR for consumer hand- sets should 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, re- source management under real-time constraints, and effi- ciency.
