定时波

A method by using 8031 single-clip microprocessor to get the syntonical bit information is presented,based on the characteristic of the modulated singal in ascending cosine envelope.

文摘：利用升余弦包络调制信号的特点，即基带信号为升余弦波，接收端可以利用这一包络，从中提取定时信息。

In this paper, the practical WDM multi-granularity traffic switching testing network is constructed and a novel method using eye diagram to monitor optical performance in the network is proposed. The method is demonstrated in the reconfigurable WDM multi-granularity traffic switching all-optical network and it results that it can realize supervision of optical signal to noise ratio, time jittering, channel power, extinction ratio and bit error rate of optical data stream of any wavelength channel in the network. The method is transparent to signal protocol and bit rates and is able to distinguish between different optical impairments.

摘要波分复用多粒度交换可重构全光网是当前光通信网发展的方向，该文构造了一种实际试验网，提出了一种&眼图法&对网中数字光信号进行全面监控的方法，并在自建WDM多粒度交换可重构全光网试验床上进行了演示，结果显示在网络重构等各种条件下均可对网中各波长通道数字信号的信噪比、定时抖动、功率、误码率等进行实时监测控制，该方法对光信号的协议和速率透明且能对各种光性能劣化进行鉴别。

It is shown that its working frequency and linear growth rate are higher than thatof common Cerenkov FEL,and for the same injection current,the linear growth rate of thissvstem and common Cerenkov FEL either decrease with increase of the gap between the dielectricand electron beam or there is an optimum gap value corresponding tO the maximum growth rate.
