Limits of data rate over a wireline channel depend on the channel characteristics, the signaling or modulation scheme, and the complexity one can afford for its implementation. This article compares two signaling schemes, namely baseband and discrete multi-tone (DMT), for two example channels, one with a smooth frequency response and one with a notch frequency response, to examine how far each can push the data rate towards the maximum achievable data rate, derived from Shannon Capacity formula.

有线通信的基带信令和离散多音性能比较

有线信道上数据速率的限制取决于信道特性，信令或调制方案，以及其实现所能承受的复杂性。本文比较了两个示例信道的两个信令方案，即基带和离散多音（DMT），其中一个信道具有平滑的频率响应，而一个信道具有陷波频率响应，以检查每个信道可以将数据速率推向最大的程度。从香农容量公式得出的可达到的数据速率。
