查询词典 timing

No additional data for frequency tracking are need, but higher estimation accuracy and low computational complexity can be obtained. Finally, a kind of optimizing joint algorithm for symbol timing, frequency synchronization and channel estimation is proposed. The false alarm probability and miss detect probability of the symbol timing are derived. We proved that the time－frequency offset domain random sequence sliding in the frequency offset direction is orthogonal with the original random sequence, and proposed a new integer frequency offset estimation algorithm. The coarse estimation methods for fractional frequency offset both in AWGN and multipath channels are proposed too.

最后，提出了一种优化的符号同步、频偏估计和信道估计的联合算法，推导了符号同步方法的虚警概率和漏检概率，给出了随机序列在时间－频率偏移域沿频率偏移方向滑动后与原序列近似正交的证明，提出了一种新的在时间－频率偏移域沿频率偏移方向进行滑动相关估计整数频偏的方法，提出了在AWGN信道和多径信道下进行小数频偏粗估计的方法，给出了小数频偏细估计的ML估计结果和利用频域PN序列取值特性的简洁的信道估计结果。

而且，选择器电路（120）按预格式化区域上记录数据的定时来选择来自端子（121）的数据图形，按用户数据区域上记录数据的定时来选择来自端子（122）的格式化数据。

In the empirical study, we find that conventional tests over reject the null when the event forecasts and event realization of all countries have high serial correlation, which means the event forecasts have the timing ability. According to the evidence of sample correlation coefficient, however, it seems that the event forecasts have no timing ability by using these the HAC robust tests.

尔后，利用实际的资料，考虑六个国家股票市场每月之报酬率发现，所有国家在事件预测值与事件实现值存在高度的序列相关下，传统检定方法出现了过度拒绝虚无假设的结果，认为事件预测值具有预测能力；而考虑序列相关问题的检定方法则认为事件预测值不具有预测能力。
