초록

In this paper we present a linear discrete bit-loading algorithm that maximizes the transmit bit rate using the channel informations to optimize the performance of the very high-speed digital subscriber line(VDSL) system. It will be useful under the constraint of a maximum transmit power for each user. When the level of crosstalk is high, the power allocation of a user changes the noise experienced by the other users in the same binder. In this case, the performance of DSL modems can be improved by jointly considering the bit and power allocation of all users.
