估计范围 meaning in Chinese
estimation range
Examples
- I ' ve heard estimates ranging from 3 to 30 times as big , with the most commonly cited number seeming to be 10
我了解到的估计范围是从3至30倍，而常常被引用的数值似乎是10 。 - The coarse frequency error estimator has a wide estimation range and may be used for initial caption . and the fine estimator can achieve nice performance in multipath environment
该粗估计器有很大的估计范围，可用于频偏的捕获；而精估计器在多径环境下能得到很好的估计效果。 - In the synchronous techniques based pilot symbols , here propose a frequency offset estimating arithmetic using discrete pilot symbols . we pick up integer times sub - carrier frequency offset from the same ofdm symbol and estimate exact
此外,在频偏估计方面,推导出短训练序列前后两段时域符号间的关系,并利用此进行粗频偏估计,使频率偏移的估计范围大大增加。 - And the corresponding improved algorithms for the above discussed methods are also provided . finally , a new combined method with better estimation accuracy and extended estimation range is also presented . simulation results show the method is feasible
在分析完以上各算法后，本文又提出了一种既保证了算法估计精度，又扩大了算法估计范围的信号载频偏差精确估计的联合方法，仿真结果验证了其可行性。 - Furthermore , this paper exploringly studies an 802 . 1 la high - speed wlan with the 54mbps data rate , and presents a sort of time synchronization and frequency offset estimation method based on the frequency domain auto - correlation of the unique preamble training sequence of 802 . 11 plcp frame ; the method have the high time precision , the wide frequency estimat ion range and short convergence process ; and moreover , it can applied to other frame communication system
另外本文还对最高传输速率为54mbps的802 . 11a高速无线局域网系统进行了探索性研究，讨论了ofdm调制技术在无线局域网中的应用；结合802 . 11a物理层数据帧结构特点，提出了一种基于前导训练符号序列的频域自相关时间和频率同步方法，此方法具有定时精度高、频偏估计范围宽和同步建立迅速等特点，也适合于其它帧通信应用场合。
