CHIL: Common-Modem Hardware Integrated Library

In recent years, there has been a large push in the U.S. Department of Defense (DoD) to more rapidly respond and adapt to changing technology advancements and emerging communications systems threats. One issue has been that traditional DoD waveform development has been stove-piped in that processing blocks are implemented to serve a single function instead of made generic and configurable to support multiple waveforms. Developing new waveforms typically requires starting from scratch almost everytime. In this paper, we present Common Hardware-modem Integrated Library (CHIL). CHIL is both a library of configurable processing blocks as well as a framework that ties these blocks together to rapidly instantiate new DoD and non-DoD waveforms. We present an overview of the CHIL framework and various components as well as provide a test-case where CHIL was leveraged to instantiate a DoD waveform.
