Welkin Sciences proposes to develop two run-time channel realization generators that are functionally equivalent to DTRAs ACIRF code. One is a software only implementation suitable for computer link simulations and test analysis applications. The other is a combination of software and FPGA-based firmware that can be embedded into existing and future hardware-in-the-loop (HWIL) fading channel simulators.

The proposed Complex Realization Generator (CReG) provides a real-time and software-based functional alternative to the Antenna-Complex Impulse Response Function (ACIRF) code. CReG generates fading channel realizations for the entire range of channel models represented by DTRA's Generalized Power Spectral Density (GPSD).
