SBIR-STTR Award

The goal of the Army STTR Phase I Project is to study and initiate commercialization of the frequency-shifted reference ultra-wideband (FSR-UWB) in short range wireless communications. The project team consists of NewLANS and the University of Massachusetts. The former is a small business with expertise in both wideband circuit design and in the commercialization of communication products, while the latter is a research university where researchers are working on the frequency-shifted reference ultra-wideband (FSR-UWB) technology. The team has identified three research challenges

UWB is a promising technology but the implementation is complex, and it is prone to jamming and interference from narrow in-band interferers. An innovative implementation of the frequency-shifted reference (FSR) UWB architecture was proposed in Phase I. The feature of this architecture is in the ease of implementation, low power consumption and the rejection of narrow in-band interferers. The interference rejection is achieved by adaptive filter which scans the UWB band like a spectrum analyzer and rejects them. Multipath and interference simulations performed in Phase I has verified the robustness of the wireless link. Phase I analysis has shown that power consumption of the proposed FSR-UWB system is extremely low. In Phase II, the FSR-UWB system will be fabricated on CMOS devices and their performance measured.
