对于某些应用，例如多媒体通信中，比特流有不同的优先级。当前的加载算法没有考虑位优先级。我们提出了一种加载算法来为具有不同优先级的比特流分配资源。通过使用传输功率最小化准则来表述负载问题并推导算法。所提出的算法可以用封闭形式进行数学表达，因此避免了密集排序。所提出的加载算法也在双绞线信道上进行了模拟。
For some applications, e.g. multimedia communications, bit streams have varying priorities. The current loading algorithms do not take bit priority into consideration. We propose a loading algorithm to allocate resources for bit streams with unequal priorities. The loading problem is formulated and the algorithm is derived by using a minimization of transmission power criterion. The proposed algorithm can be mathematically expressed in a closed form and therefore intensive sorting is avoided. The proposed loading algorithm is also simulated over a twisted-pair channel.
