提出了一种新的比特分配算法，用于通过并行、独立信道（例如多载波传输）进行未编码传输。与最先进的加载算法相比，它基于位级容量，旨在最大化所谓的并行解码容量。该算法可以非常有效地实现，并且比现有方法所需的复杂性显着降低。数值结果显示在误码率方面的性能与已建立的位加载算法相当。
A new bit allocation algorithm for uncoded transmission over parallel, independent channels (e.g., multicarrier transmission) is proposed. In contrast to state-of-the-art loading algorithms it is based on bit-level capacities and aims at the maximization of the so-called parallel decoding capacity. The algorithm can be implemented very efficiently and requires significantly lower complexity than existing approaches. Numerical results show a performance in terms of the bit-error ratio comparable to established bit-loading algorithms.
