Evolving WCDMA for Extreme Mobility Navy SBIR FY2012.2 Sol No.: Navy SBIR FY2012.2 Topic No.: N122-147 Topic Title: Evolving WCDMA for Extreme Mobility Proposal No.: N122-147-0181 Firm: TrellisWare Technologies, Inc. 16516 Via Esprillo Suite 300 San Diego, California 92127-1708 Contact: Marcus Urie Phone: (858) 753-1623 Web Site: www.trellisware.com Abstract: The Mobile User Objective System (MUOS) will provide the warfighter with the tactical ability to communicate in disadvantaged environments. The underlying MUOS concept -- namely, adapting a powerful commercial cellular waveform to a military grade infrastructure -- has applications beyond the initial system deployment. For example, the development of ruggedized WCDMA base station processing payloads would allow the ground station processing to be done aboard the satellite. Furthermore, the geosynchronous satellites of the MUOS system could be replaced by satellites in alternative orbits (e.g., the Molniya orbit) or even unmanned aerial vehicles and aerostats. In order to realize these applications, however, significant innovation is required in WCDMA receiver signal processing algorithm design. To this end, TrellisWare proposes to develop a turbo Rake receiver structure that combines Per-Survivor Processing (PSP) and Adaptive Iterative Detection (AID) to enable reception of the MUOS waveform in severe Doppler environments. Benefits: The technology developed under this program has a natural avenue for commercialization in the government sector. TrellisWare proposes to work with the manufacturers of military cellular communication systems to integrate the algorithms prototyped in Phase II with their hardware. In this effort, we will leverage the relationships that we have developed will all of the major Prime Contractors as a result of our JTRS Solider Radio Waveform work. The Navy's vision for operating MUOS satellites in the Molniya orbit offers a compelling commercial application as well. In particular, cellular base stations could be mounted on unmanned aerial vehicles - or even aerostats - and used to alleviate areas of temporary congestion at low cost (e.g., stadiums and parks). Furthermore, aerial basestations could provide emergency communications in the event of natural disasters when ground stations are damaged. In commercializing the receiver enhancements developed under this program, we will leverage the relationships that we built previously with cellular providers and commercial handset manufacturers when we worked on Single Antenna Interference Cancellation (SAIC) problems for GSM networks.
