Made it fully SMP compliant and installable as an ordinary device driver rather than as a modification to the operating system kernel. Obtained a four-fold improvement in transmission throughput for wireless communications by using an approximate scheme, based on table lookups, for assembling transmitted waveforms. By avoiding the computation of complex waveforms at runtime, this scheme improves performance and reduces power consumption. Developed a prototype RadioActive network providing IP over a dynamically adjustable wireless link. Applications can control the frequency and modulation format on the link in response to packet loss caused by environmental interference in a particular frequency band.
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.
