在本文中，我们将数字用户线路 (DSL) 的多用户功率控制问题表述为非线性互补问题 (NCP)。我们研究了所得到的 NCP 属于 P 0 类且其解是 B-正则的条件。 NCP 公式使得使用牛顿型平滑方法 (SM) 有效计算纳什均衡解成为可能。在我们的计算机模拟中，SM 对于强干扰的存在似乎比现有的同步注水方法更加鲁棒。我们还提出了 NCP 公式的扩展，它可以显着提高 DSL 系统的速率和性能。本研究的部分内容是作者在加拿大安大略省汉密尔顿市麦克马斯特大学电气与计算机工程系进行的。这项研究是作者在访问加拿大麦克马斯特大学时进行的。
In this article, we formulate the problem of multiuser power control for digital subscriber lines (DSL) as a nonlinear complementarity problem (NCP). We study conditions under which the resulting NCP belongs to the class P 0 and its solution is B-regular. The NCP formulation makes it possible to use the Newton-type smoothing methods (SMs) to efficiently compute a Nash equilibrium solution. In our computer simulations, the SM appears much more robust to the presence of strong interference than the existing synchronous water-filling method. We also present an extension of the NCP formulation, which can lead to substantial increase in the rate sum performance of the DSL system.
