The Stanford Dynamic Spectrum Management (DSM) allows adaptive allocation of spectrum to various users in a multiuser environment as a function of the physical-channel demographics, to meet certain performance metrics. By contrast, static spectrum management necessarily fires spectrum allocation based upon a worst-case analysis. Many communication systems, for example DSL (Digital Subscriber Line), use static spectrum management to ensure that mutual degradation between services sharing a physical medium are within acceptable levels. Necessarily, such worst-case spectrum management reduces achievable data rates and symmetries in DSL. Our group is currently investigating the possible performance improvements that DSM can bring to multiuser environments, with particular emphasis on DSL and wireless transmission channels. [ - ]
