Dynamic Programming Based Multi-User Resource Allocation for Partial Crosstalk Cancellation in VDSL

This letter deals with multi-user computational resource allocation for partial crosstalk cancellation in the vectored VDSL2 systems. We re-look at the multi-user rate optimization problem and provide a dynamic programming based optimal algorithm with deterministic computational complexity, which is...

Description
Summary:This letter deals with multi-user computational resource allocation for partial crosstalk cancellation in the vectored VDSL2 systems. We re-look at the multi-user rate optimization problem and provide a dynamic programming based optimal algorithm with deterministic computational complexity, which is quadratic in the problem size.
