Include Baidu, we are not each enterprise is cast very well and truly, but comparatively, I still think this domain inside in broadband and wireless domain inside can have a lot of a lot of opportunities, actually this also is the feeling of commonsensible sex, myself feels computer is already enough and powerful, but I did not feel the mobile phone is enough and powerful, I also did not feel bandwidth is in the home high to me inside online whats can do the broadband, the edge includes video here, also include to be in wireless when, you are not done in on the road a lot of things, the meeting side here has a lot of a lot of opportunities to come out.

包括百度，我们并不是每一个企业都投得非常准确，但是相对来讲，我还是认为这个领域里边在宽带和无线领域里边会有很多很多机会，其实这个也是常识性的感觉，我自己感觉电脑已经足够强大了，但我并没有感觉到手机足够强大，我也并没有感觉到带宽高到我在家里边宽带上网什么都可以干了，这里边包括视频，也包括在无线的时候，你在路上很多事情做不了，这里边会有很多很多机会出来。

Bandwith The amount of data that can be passed along a communications channel in a given period of time.

带宽 在指定时间内通过通信渠道的数据总量。

Bandwidth augmentation is the ability to add another communications channel to an already existing communications channel.

带宽增加是指可以在一个现有的通信信道中增加额外的通信信道。

This can significantly enhance user experience over a bandwidth constrained communications channel.

这可以通过带宽通信通道的限制大大提高在用户体验。

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。

Using bi-imaginary number representation, complex multiplication is simplified into two multiplication, instead of four ones in the previous method.

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。

The area user that radiate of cloud computation center enclothes needs to put forward his to want to use what network to serve only, the divine water in this pond helps you press require calculation, by want a service.

王涛打了个形象的比喻：我们可以把云计算中心看成一个虚拟化的资源池，池子里有各种网络计算资源、网络存储资源、网络带宽资源……云计算中心辐射覆盖的区域用户只需提出自己想要使用什么网络服务，这个池子里的神水就帮你按需计算、按需服务。
