摘要
在详细研究注水定理的基础上,提出了DMT系统中一种离散量化度是近似注水分布的分配算法,不仅使性能有所提高,而且复杂度大大降低。
A new practical algorithm is presented which approximately matches the water-pouring distribution and can also solve the discrete bit loading problem in DMT systems. The simulation results show this algorithm has better performance and lower complexity.
