We propose a novel, high performance, and standalone system for improving close air support (CAS) effectiveness. We have several important elements. First, we propose a standalone noise cancellation device (NCD) that can be inserted between the handset and the transceiver. That is, the handset output is connected to the NCD and the NCD output is connected to the transceiver. As a result, there is no change to the existing communication system. The NCD is self-powered from its own battery and equipped with one or two microphones and a digital signal processing (DSP) chip to process the signals from the handset mic and the mics in the NCD. Second, we have extensively evaluated numerous algorithms in Phase 1 for battlefield noise suppression. The best algorithms will be implemented in DSP in Phase 2. A hardware prototype with small size and low weight (
