Abstract : based on the iterative bit - filling procedure, a computationally efficient bit and power allocation algorithm is presented. the algorithm improves the conventional bit - filling algorithms by maintaining only a subset of subcarriers for computation in each iteration, which reduces the complexity without any performance degradation. moreover, a modified algorithm with even lower complexity is developed, and equal power allocation is introduced as an initial allocation to accelerate its convergence. simulation results show that the modified algorithm achieves a considerable complexity reduction while causing only a minor drop in performance
文摘:基於迭代的比特和功率分配機制，提出了一種低復雜度的比特和功率分配演算法.與傳統的迭代分配演算法不同，該演算法在每次迭代中只需要比較幾個特定的子載波.該方法在保持傳統迭代演算法性能的前提下極大地減小了迭代分配演算法的復雜度.此外，通過選擇等功率分配方案作為初始方案加快了演算法的收斂速度，進一步降低了演算法復雜度.模擬結果表明，提出的改進演算法在基本不犧牲系統性能的前提下有效地降低了演算法復雜度 -
Dispersed elements like cd, ge, and ga were transported in the form of chlorine complexes or adsorbed by chlorine complexes of pb and zn. thermal degradation of organic materials resulted in the generation of ch4 which further initiated the reduction of sulfates and the precipitation of sulfides
Cd 、 ge 、 ga等分散元素可能形成了部分氯化物絡合物或者被pb 、 zn的絡合物吸附而隨之一起遷移；含礦熱液帶來的熱能使礦化圍巖中有機質發生熱降解作用產生甲烷，從而導致硫酸鹽的還原和金屬硫化物的沉澱。
