Code division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, which is where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth). To permit this to be achieved without undue interference between the users CDMA employs spread-spectrum technology and a special coding scheme (where each transmitter is assigned a code). Each user in a CDMA system uses a different code to modulate their signal. Choosing the codes used to modulate the signal is very important in the performance of CDMA systems. The best performance will occur when there is good separation between the signal of a desired user and the signals of other users.

AntColonyAlgorithmforSolvingQoSRoutingProblem
在状态转移规则的基础上,局部更新规则和全局更新的蚁群算法的规则,我们提出一个IM证明蚂蚁的最低成本的服务质量蚁群算法(QoS)的路径用于解决网络路由问题与延迟以及背包约束中进行模拟。约52.33%蚂蚁找到成功的QoS路由。并收敛到最佳。(based on the state transition rule,the local updating rule and the global updating rule of ant colony algorithm ,we propose an im proved ant colony algorithm of the least cost quality of service(QoS)unicast routing.The algorithm is used for solving the routing problem with delay.delay jitter.bandwidth,and packet lOSS constrained. In the simulation,about 52.33 ants find the Successful QoS routing .and converge to the best. It is proved that the algorithm is efficient and effective.)

关于蝶形宽带微带天线的设计
索引:蝶形宽带微带天线. 设计方案 排列效率
摘要:现在提出一种基于绝缘体衬底的有限长度的宽带微带天线的设计方法。这种方法快速、对计算精度要求较低,是建立在一蝶形天线进行二等分而形成的两个梯形天线的 。首先设计出单边的梯形部分,然后制作出相同的另一部分并在其顶点处将其连接。与理论计算相比在X波段上实验测量表现得很好。其有效带宽达到10.6%。
(One approach to an antenna book starts with a discussion of how antennas radiate. Beginning with Maxwell’s equations, we derive electromagnetic waves. After that lengthy discussion, which contains a lot of mathematics, we discuss how these waves excite currents on conductors. The second half of the story is that currents radiate and produce electromagnetic waves. You may already have studied that subject, or if you wish to further your background, consult books on electromagnetics.The study of electromagnetics gives insight into the mathematics describing antenna radiation and provides the rigor to prevent mistakes. We skip the discussion of those equations and move directly to practical aspects. )
