Abstract
The purpose of this proposal is to present a novel and promising noise attenuation solution for the first responders to effectively communicate in high-noise operation environment regardless of the communications mode (through radios in push-to-talk mode, VOX mode and without radios). For different application scenarios, we propose two possible solutions to handheld and hands-free applications, respectively. The proposed noise cancellation solution is based on our experiences in previous research and similar product design. Our research will be focused on improving signal-to-noisy ratio (SNR) for high-noise environments and extending the battery life. At the end of Phase I, all algorithms will be implemented and tested in an existing hardware platform. Also, preliminary hardware designs will be finished and all major chips for the device will be selected in Phase I.
