| Abstract: |
The objective of this proposal is to present a novel and promising solution for a noise cancellation device (NCD) that could be easily mounted on the top of military radio's handsets used by the Joint Terminal Attach Controller/Forward Air Controller (JTAC/FAC) personnel and effectively filter out noise resulting from artillery fire and transmit voice only. To ensure the quality, the proposed device has three noise reduction and cancellation modules. The first one is a microphone array with adaptive beam-forming which utilizes the spatial domain information for noise reduction. The second one is a noise cancellation unit which utilizes the tempore domain information and adaptive filtering technology. The last one is an intelligent noise reduction system especially for military sound reduction which utilizes our speech recognition technology. Since the company has developed three microphone arrays products with noise reduction and cancellation, many of our existing technology, algorithms, software tools, and hardware platforms can be used to this project directly to ensure the success and quick deployment. |
| Benefits: |
The proposed system has a potentially large market for military operation and commercial applications. We will first file patents for our proposed technology and then manufacture the system for military operations. We will further introduce the developed technique to commercial radio transceivers, law enforcement radio transceivers and commercial radio devices. In addition to military and security applications, we will introduce our technology to handheld devices, such as wireless phones, PDAs, notebook computers, etc. The potential market is huge. |
