For reducing the complexity due to the existence of multidelay paths, a simplified algorithm is suggested using Equivalent one-path channel vectors (EOCVs) to replace multipath channel vectors.XiaoyingWANGShuxunChinese Journal of ElectronicsSUN Xiaoying,WANG Shuxun.Space-time Coding Combined with Domn...
2.If N numbers are stored in a singly linked list in increasing order, then the average time complexity for binary search is O(logN). TF 因为链表不支持随机存取,而O(logN)的算法严重依赖于随机存取,所以不可能完成。 3.If keys are pushed onto a stack in the orderabcde, then it's impossible...
divergence, PDEs, Dirac’s bra-ket operators (〈 , 〉). This fundamentals of data science research project will explore time-complexity and inferential uncertainty in modeling, analysis and interpretation of large, heterogeneous, multi-source, multi-scale, incomplete, incongruent, and longitudinal ...
Space-time coding (STC) promises improved performance in wireless fading channels. STC has been introduced successfully to direct-sequence code-division-multiple-access (DS-CDMA) systems. The large complexity of the jointly optimal multiuser space-time block decoder motivates the consideration of subopti...
enables both the maximum multiantenna diversity and the maximum multipath diversity. Although this maximum diversity can only be collected by maximum likelihood (ML) detection, we pursue suboptimal detection by means of space-time chip equalization, which lowers the computational complexity significantly....
Multiply lensed images of a same source experience a relative time delay in the arrival of photons due to the path length difference and the different grav
Such an approach, though formally elegant, becomes prohibitive or even impossible as the complexity of the equations increases, especially for multidimensional problems and for relativistic hydrodynamics and magneto-hydrodynamics. On the contrary, in the modern reformulation of ADER (Dumbser et al. 2008...
在广义相对论中,度规张量场可以看作是在时空wash每一点为该点附加了一个内禀的线元规范ds^2=g_{ij}(x)dx^idx^j。根据广义相对论的基本假设,这个规范应当是坐标无关的,也就是说,不同的观测者使用不同的坐标系时,所测量的线元\sqrt{ds^2}应当是相同的。从这里我们可以看出,对于任意允许的坐标变换:x'^i...
Let's see another complicated aspect of MethodTable: Interface implementation. It's made to look simple to the managed environment by absorbing all the complexity into the layout process. Next, we'll show how the interfaces are laid out and how interface-based method dispatching really works. ...
