the paper introduces long curtate new unequal ofdm system.adopts long curtate unequal benefit to be not to require that the second order adding the circulation prefix,being therefore likely to lead into period stationarity,making use of signal therefore in launching an array,counting characteristic property realizing blind estimation of route.this technology includes three kinds of method : subspace decomposition,correlation matching,and maximum likeewise,monte carlo simulation show that whentheeb/no is low,function is better than the other kinds of method.

摘 要：提出一种采用不等长分组新的ofdm系统。采用不等长分组的好处是不需要加循环前缀就能在发射序列中引入周期平稳性，因此，可利用信号的二阶统计特性实现信道盲估计。信道盲估计主要分子空间分解、相关拟合和最大似然三种方法。结合monte carlo仿真表明，在信噪比较低时，结合子空间分解方法计算出的误码性能比其余两种方法好。

结果表明，经硫酸亚铁还原处理后再用钢渣处理比单纯用钢渣处理的效果明显提高，采用钢渣／总铬质量比为40的100目钢渣处理经硫酸亚铁还原后的含铬废水，总铬和Cr^6＋去除率分别达79％和84％，采用钢渣柱进行的两级淋滤实验进一步表明该方法可作为工业上含铬废水处理的预处理段。

Crown ether was introduced to copolymerize with the monomer of styrene owing to which can associate with silver ions. The silver ions were in-situ reduced to silver nanoparticles by UV light. Then silver nanoparticles were led on the surface of polystyrene latex particles. The vertical precipitation was employed to get the spheres self-assembled into close packed colloidal crystal with a face centered cubic structure identified.
