Extending the SCA core framework inside the modem architecture of a software defined radio

Extension of the Software Communications Architecture (SCA) core framework inside of the modem architecture of a software defined radio requires special consideration for managing the non-CORBA-enabled devices. This is especially true of devices that maintain direct hardware connections between each other in support of the high-speed low-latency communications required by many waveforms. This article illustrates the application of the SCA core framework for these types of modem architectures, including aggregating devices in support of direct hardware interconnects between components and the incorporation of a switched fabric communications infrastructure within the overall modem architecture.
