crlb meaning in Chinese
cramér-rao下限
Examples
- The theory of soplat using frequency rate is discussed in chapter 2 . based on this theory , this chapter studies the observed discrete - time signal . the crlb of continuous wave and coherent pulses frequency estimation are also studied
论文第二章讨论了利用频率变化率的单站无源定位原理,在此基础上,介绍了单站无源系统中接收信号的模型,并分析基于各模型的频率估计的cramer - rao下界。 - Secondly , based on the limitations of single location technique and the characteristics of chan and aoa algorithins , a hybrid tdoa / aoa and a toa / aoa location algorithin are proposed , and the corresponding carb theoretical bounds of these algorithms are derived
其次，通过分析单一定位技术的局限性，基于chan算法和aoa算法特点，提出了一种tdoa aoa混合定位算法和一种toa / aoa混合定位算法，给出了这两种算法定位性能的crlb理论界。 - A new method for doa estimation in certain nonstationary environments is presented in chapter 4 . the maximum likelihood ( ml ) estimations of doa ' s of multiple rapidly moving sources is derived and the theoretical variance of angle estimation and the corresponding cramer - rao lower bound ( crlb ) are also given . its simulations show that this parametric technique is able to resolve closely spaced sources
提出了一种非平稳环境下的最大似然doa估计方法，该算法适合于时变doa的情形，并分析了其参数估计性能，给出了角度估计的渐进方差的解析表达式，表明了常规的最大似然doa估计是本文的一特殊情形。
