直接序列码分多址是第三代移动通信系统的优选多址工作方案。

Multiple trials is the basic concept of many parallel simulated annealing. It is to perform multiple trials at the same time to search acceptable solutions. The division simulated annealing with no communication and The clustering simulated annealing are two common types of parallel simulated annealing methods. The division simulated annealing with no communication makes each processor generate its own adjacent solution from its own current solution and compute the acceptance probability for a adjacent solution. Each of the processors searches solutions without communicating each other. Clustering simulated annealing makes each processor generate its own adjacent solution from a common current solution and compute the acceptance probability for each adjacent solution. Then, it decides which adjacent solution should be used to replace current solution according to a pre-specified rule.

许多平行模拟退火法之理论依据为多向试验，利用同一时间探索更多方向的试验来拓展搜寻的广度或深度，不进行沟通的分工模拟退火法(the division simulated annealing with no communication)以及丛集模拟退火法(the clustering simulated annealing)皆为平行化的模拟退火法，前者定义为各个处理器针对各自的起始解进行搜寻，产生各自的搜寻序列，在搜寻过程中处理器不进行任何沟通，各处理器仅针对自身之目前解进行搜寻；而后者定义为让所有处理器针对同一目前解进行运算搜寻各自的可能解，并各自决定其产出解之接受机率，最后根据事先决定之规则进行沟通比较，挑选其中一个可接受解取代目前解。

For example,the maintenance of multiple networks can require additional staff.often,this staff must be trained on multiple vendor technologies,sometimes requiring parallel groups specializing in each （72） hence,additional maintenance procedures must be maintained and administrative records are （73） the duplication of trasport facilities to carry （74） network traffic is an inefficient use of resources and,not surprisingly,more technologies installed in a central office mean the necessity for more physical space,and an increase in power connections and power consumption.migration of these （75） network elements to IP-based DCns is alogical strategy

例如，维护多个网络需要增加工作人员。通常这些人员必须培训，以便熟悉多种制造商技术，同时还需要熟悉不同平台的许多工作小组。因此，额外增加的维护过程使得各种管理记录激增。承载着不同网络通信的多种传输设施造成了资源的无效使用。很自然的推论就是，更多的技术装置配备在交换局中意味着需要更大的物理空间，增加了动力设备和电源消耗。这些遗产网络元素逐步迁移到基于IP的DCN是符合逻辑的策略。

In this paper, firstly we researched the relationships of the communicating distanceand the channel characteristic, the effect of the multiple scattering to the laserpropagation, the requirement of the laser communication to the ATP system and theway to determine the angular dispersion and receive field of view.
