Moreover, the high frequency radio can also be used in the optical label switching. The subcarrier multiplexing optical label and optical carrier suppression and separation optical label are based on modulating lightwave by radio, which were studied much and maybe have a good future.

另外，在光标记交换领域，利用高频的无线信号调制光波实现的副载波光标记和光载波抑制光标记现已有一些研究，这两种标记实现方案有很好的应用前景，但还有一些问题需要深入研究，本论文对SCM光标记信号的传输距离受限问题和OCSS光标记分组的全光波长变换问题进行了深入研究，并得到了一些有价值的结论。

After all, the track has smashed records, becoming the biggest radio airplay hit in the history of North American Top 40 radio, according to Billboard.

据Billboard的消息，这首单曲已经打破了很多项记录，成为在北美最好的40家电台的史上点播率最高的大热门。

In wireless broadband digital communication, Inter-Symbol Interference caused by time disperse of radio channel is one of main factors that limit bandwidth of communicated information and system performance of communication. In receiver, Orthogonal Frequency Division Multiplexing system can easily cancel ISI and equalize frequency-selective fadings that are both caused by time disperse of radio channel.

在这一系统中，无线信道时延扩展引起的符号间干扰是限制传输性能和信息速率的主要因素之一；而在消除符号间干扰和均衡由无线信道时延扩展引起的频率选择性衰落方面，正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)技术具有明显优势。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
