Dynamic Spectrum Management (DSM) is the application of multi-user communications’ signal processing to the problem of cross-talking transmission paths. DSM has been used with significant success in binders of cross-talking DSL circuits, and is a predecessor to dynamic spectrum access in wireless transmission. This talk will focus on the methods used for the 3 standardized levels of DSM, which address (1) outages and transmission-path stability, (2) politeness and adaptive power-spectra control, and (3) coordinated vector (or multiple-input, multiple-output) removal of crosstalk noise. DSM thus provides signal-processing opportunities in integrated circuits and network-management software that will be described.
