      Prior work has shown that software defined radio has the ability to reduce the size, weight, power and cost of telemetry and avionics. We propose a virtualized transceiver architecture that supports multiple concurrent software defined radio (SDR) applications running on shared SDR hardware. This paper applies the concept of virtual transceivers to SDR for telemetry and avionics. The proposed design allows for transceivers to be shared between different SDR applications by taking advantage of time separation and frequency adjacency. This paper addresses the system layout, hardware selection, and software organization. Improvements include a scalable and considerations for both redundancy and upgradability.
