Applications can also load new modulation schemes on the fly. This estimator replaces PLLs used in traditional DSP hardware, which perform an inaccurate computation on every cycle, by a software estimator, which performs a more accurate computation that can be used over an extended interval, thereby improving performance and reducing power consumption. Seek funding to continue work on SpectrumWare. A proposal submitted to BAA 99-04 was deemed selectable, but has not been funded. Build additional virtual radios, for example, a 20Mbps wireless digital communication channel or an anytime, anywhere patch panel for use in disaster relief or to provide interservice compatibility.
Discussions are underway with several companies concerning cooperative efforts.
Vanu Bose, who received his PhD this year, has formed a company, Vanu, Inc. to provide software radio solutions for a wide range of computationally intensive, real-time wireless communications systems. John Guttag gave a keynote address at the 11th Annual DoD Software Technology Conference in Salt Lake City. He gave a presentation on SpectrumWare to a large audience, containing many industry representatives, at the 35th Anniversary Celebration for the MIT Laboratory for Computer Science. The Spectra software environment, together with documentation and sample applications, will be available for distribution by the end of 1999.
