Dynamic Spectrum Management (DSM) is emerging as a key component in next-generation digital subscriber line (DSL) technology. Because DSL twisted-pair binder channels are chiefly interference-limited, the multiuser performance and compatibility of DSM is of foremost importance. Although these issues are well understood for Static Spectrum Management (SSM) used in state-of-the-art DSL, existing techniques are not amenable to the study of Dynamic Spectrum Management.

520 # $a Dynamic Spectrum Management (DSM) is emerging as a key component in next-generation digital subscriber line (DSL) technology. Because DSL twisted-pair binder channels are chiefly interference-limited, the multiuser performance and compatibility of DSM is of foremost importance. Although these issues are well understood for Static Spectrum Management (SSM) used in state-of-the-art DSL, existing techniques are not amenable to the study of Dynamic Spectrum Management.
520 # $a This thesis presents novel interference analyses that characterize the performance of two classes of DSM: when multiuser interference is treated as noise, and when multiuser encoding and decoding ("vectored transmission") is performed. A game-theoretic framework is adopted whereby Nash equilibria of certain strictly-competitive games characterize the "worst" interference scenarios.
520 # $a When interference is treated as noise, this approach yields a lower bound that is close to performance in the field. Numerical results are presented for two relevant scenarios: an upstream VDSL deployment exhibiting the near-far effect, and an asymmetric DSL remote terminal (RT) deployment with long central office (CO) lines. The results show that the performance improvement of DSM over SSM techniques in these channels can be preserved by appropriate distributed power control, even in worst-case interference environments.
520 # $a When multiuser encoding and decoding is feasible, results are obtained both for downstream and upstream transmission. For downstream transmission, a worst-case throughput (sum rate) is obtained from the Nash equilibrium of a strictly-competitive game. In upstream transmission, a general weighted sum-rate is similarly considered. Partial uniqueness properties of the Nash equilibria of each game are developed.
