非均匀量化的软判决Viterbi译码

根据信道转移特性的规律，本文提出一种采用非均匀量化区间的软判决Ｖｉｔｅｒｂｉ译码方案，对原有十六电平的均匀量化的量化区间进行修改，尝试了两种非均匀量化方案，计算机模拟表明：依据信道的统计特性合理的确定非均匀量化区间，不仅可以减少硬件实现的复杂性，而且可以以较少的量化区间取得更好的译码效果。

A simple spectroscopic method for the quantification of gold nanoparticle number concentration in water and fetal bovine serum solutions

In this work,we developed a facile and low-cost method with sufficient sensitivity for the quantitative determination of gold nanoparticles(GNPs)number concentration in water and fetal bovine serum solutions.The Au(III)digested from GNPs was reduced to Au(I)presumably by the thiol group of 2-mercaptobenzimidazole,then the Au(I)–thiolate complex was formed,the concentration of which is determined by absorbance at 300 nm.The number concentration of GNPs can be converted using microscopic images and simple calculations.The interference of serum can be avoided in this method.The limit of detection(LOD)of GNPs was calculated as 2.1 910-12mol/L in water solution and 1.3 9 10-11mol/L in fetal bovine serum(FBS)solution.This method provides a simple and fast way to determine the concentration of GNPs,which can be in carried out in the routine laboratory practice.
