ABSTRACT Over the last few years much attention has been paid to the development of the technologies for Community Antenna Television networks. New technologies that can be used to support data communication service over CATV networks are developed. The new Hybrid Fiber Coaxial technology is spreading out rapidly in CATV networks. The usage of fiber provides large bandwidth and thus enables some new services to be delivered along with television broadcast. The CATV networks are expected to support diverse traffic with various service requirements.

随着新技术的不断发展，人们希望能够利用有线电视网络提供新的业务，HFC技术在有线电视网络中的广泛使用使得有线电视网络的带宽增加，也使得有线电视网络除电视广播外还能够提供其他的服务，这些服务的服务质量要求各不相同，如：数据服务要求低的丢失率，对延时的要求较低；而语音服务可容忍一定的丢失，但对延时、延时抖动有严格的要求，因此需要开发新的协议。

to reduce the impact of carrier frequency offset in ofdm system,this thesis designs a new carrier frequency offset estimation scheme for ofdm system.the carrier frequency offset estimation includes acquisition and tracking.we adopt variable step size adaptive algorithm.the acquisition range of the proposed algorithm is as large as one half of the overall signal bandwidth.through this method we can not only avoid the feedback by using forward error correction,but also reduce the times of complex multiplication in order to reduce the power consumption of the system.this algorithm not only has low complexity and fast convergence nut also can improve the demodulation performance of ofdm system.computer simulation illustrates the superior performance of the proposed algorithm with regard to estimation accuracy in both awgn channel and multi—path channel.

摘 要：为了减小正交频分复用系统受频率偏差的影响，在ofdm系统中设计了一种新的载波频偏估计算法。频偏估计包括跟踪和捕获两个阶段，文中采用变步长自适应算法来进行跟踪，这个跟踪算法的捕捉范围是整个信号带宽的一半。通过此方法，不但可以利用前向纠错的方式来避免反馈，而且可以缩减复数乘法的次数以降低计算复杂度和系统功耗。该方法运算复杂度低，并具有较好的收敛性，能改善odfm的解调性能。从计算机的仿真效果可以看出无论是在awgn信道上还是在多径信道上都表现出了卓越的性能。

Personage of strange tiger interior discloses, strange tiger has been in the computer room of 20 many cities of countrywide purchased more than 2000 servers, bandwidth achieves 50G, borrow this to establish this " cloud computation center ".

奇虎内部人士透露，奇虎已经在全国20多个城市的机房中购置了超过2000台服务器，带宽达到50G，借此组建自己的"云计算中心"。【以下内容为IT者网站提供英文翻译，未经授权请勿转载

The SAN makes it true that storage resources can be devided from servers, and can provide high performance data pipe with 100 MB/s and shared storage devices managed concentrically. This makes data access, backup and restore will not reduce performance of network largely. This removes people抯 misgiving for bandwidth of network.

SAN使存储资源与服务器分离，可以提供100兆字节／秒的高性能数据管道和共享的集中管理的存储设备，使得数据的访问、备份和恢复不会大幅度降低网络性能，消除人们对网络带宽的顾虑。

This is to ensure that no subscriber can congest the bandwidth at all times.

他们有权利拒绝提供格外的流量给你。

The user's utility is a function of his data throughput, thus the bandwidth resource utilization problem is modeled as a utility based constrained maximization problem, called a system problem.

通过设置站点吞吐量的对数效用函数，将带宽资源的有效利用问题建模为系统效用最大化问题；应用最优化理论将此系统问题等效为可分布式求解的用户问题，即各站点只须独立选择最大化其净效用的竞争参数，则系统整体效用也获得最大化。
