This dissertation presents contributions to some strategies of spectrum management
which have received few attention in the literature: power minimization and noise margin
maximization. Regarding power minimization, about 60% of the total power drained by the
DSL transceivers are used in the transmission. The contribution of this dissertation with
respect to this field was to prove mathematically that the algorithms of rate maximization
can also be used to minimize power. This way, the development gap between these two
modes of operation vanishes, turning them in the same level of development. The second
contribution of this dissertation is about the noise margin maximization, in order to optimize
the stability of DSL networks. In this direction, this dissertation presents a new algorithm
of multiuser margin maximization, which shows superior performance when compared to a
previous algorithm published in the specialized literature. |
