一种改进的家庭基站频谱分配算法
An Improved Femtocell Spectrum Allocation Algorithm
 [PDF]


Hans Journal of Wireless Communications (HJWC) , 2012, DOI: 10.12677/hjwc.2012.21005
Abstract: 家庭基站(Femtocell)被认为是下一代通信系统新兴技术之一,为我们解决室内覆盖问题提供了一种有效的方法。而要想在已经存在的宏蜂窝网络中成功的部署家庭基站系统,仍然面临许多问题,比如,小区之间的频谱划分来最大化频谱效率最小化小区干扰,切换和功率控制等。本文从频率复用的角度,将软频率复用方法(SFR)应用到Femtocell两层网络的频谱分配算法中,给宏小区的内部区域和外部区域分配不同的功率,提出一种改进的基于SFR的家庭基站频谱分配算法。仿真结果和分析显示我们所提出的频谱分配算法能够提高宏用户的性能,最小化家庭基站的配置对宏用户性能的影响,保证小区边界用户的性能,增大系统容量。
Femtocell is considered to be one of emerging technologies in next generation communication systems. It provides an effective method for us to solve the indoor coverage problem. However, deploying the femtocell system in the existing macrocell network still faces many problems, such as spectrum allocation between cells to maximize spectral efficiency to minimize cell interference, switching between cells and power control. In this paper, according to the frequency reuse method we use the soft frequency reuse (SFR) method to our two-tier femtocell network. Allocating different power to the internal area and external area of macrocell, we propose an improved femtocell spectrum allocation method. Simulation results and analysis showed that the proposed spectrum allocation algorithm can raise the performance of the macro users and increase the system capacity.

Abstract:

田园景观指的是以田园为载体,以生产农业物质产品和农业审美产品为目标,通过农作物与田块、田埂、沟渠、林带、道路和机井、棚架、电网、房屋等生产设施的合理排列、美学组合,形成的田园风光。它是田园;是种植农作物的田园;是种植农作物,生产农产品的田园;是既生产农业物质产品,又生产农业审美产品的田园。它以整齐、图案、特写、文化和园林的形式表现着美,具有田园性、依存性、多样性、风光性和园林性等特征。

The rural landscape refers to the country as the carrier, to the production of agricultural products and agricultural aesthetic products as the goal, and through reasonable arrangement and aesthetic combination of the crops and fields, ditches, ridge of field, forest, roads and wells, scaffolding, power, housing and other production facilities, thus the pastoral scenery is formed. It is the garden where crops are growing; and not only growing crops and agricultural production, but also agricultural material products and agricultural aesthetic products are the production of the garden. It displays the beauty by the forms of orderliness, pattern, feature, culture and landscape with the characteristics of pastoral, dependence, diversity, scenery and landscape.

基于Wallis原理改进的匀光算法
Improved Dodging Algorithm Based on Wallis Principle
 [PDF]


Geomatics Science and Technology (GST) , 2015, DOI: 10.12677/GST.2015.33008
Abstract: 光照不均匀现象是遥感影像获取中常见的一个问题,光照不均匀影像往往存在反差不均匀现象,而Wallis滤波器对反差不均匀影像有特殊作用,故可以采用Wallis原理对光照和反差不均匀影像进行处理。经典的Wallis匀光结果影像也存在“块效应”和整体色调偏移等问题,本文提出一种基于Wallis原理改进的匀光算法,在消除光照不均的情况下也能改善反差不均匀现象。实验表明,改进后的匀光算法处理的结果影像能有效的实现光照和反差一致。
The uneven illumination phenomenon is a common problem in remote sensing image acquisition, and the uneven illumination image often has uneven contrast phenomenon, while Wallis filter has a special role for the uneven contrast image, it can adopt the Wallis principle to process the light and uneven contrast image. The results of the classical Wallis algorithm also have some problems, such as the “block effect” and the migration of overall tone. This paper proposes an improved dodging algorithm based on Wallis principle, and the experiment results show the result image which is processed by the improved dodging algorithm can realize illumination consistency and contrast effectively.
