High Capacity Communications Capability (HC3) Government Reference Architecture (GRA): Alternatives for Third Partv A2G Waveform Porting

This paper describes the alternatives for implementation of third party Above 2 GHz (A2G) waveform porting over software programmable modems. With the advent of software radios, Government software standards have been proposed, and are evolving, which are intended to facilitate reuse and portability. To date, these steps have achieved limited effectiveness in maximizing reuse and reducing cost, particularly in A2G terminal designs. The fundamental problem that all new terminal programs face is the lack of an efficient methodology to leverage and/or reuse pre-existing efforts, without incurring substantial redevelopment costs particularly but not limited to waveform development. This paper will review the GRA and COTS alternatives with respect to terminal architecture for third party A2G waveform porting. Particular emphasis will be placed on existing standards ability to support the alternative (i.e. SCA).
