Grassmann流形和Stiefel流形中的球面填充界
Sphere packing bounds in the Grassmann and Stiefel manifolds
摘要：
应用黎曼几何机器的体积估计的曲率，包装/代码的最小距离的Grassmann和Stiefel流形的界限将推导和分析。在空时分组码的上下文中，这导致最小距离下限作为分组长度的函数单调增加。这就要求代码设计使用较大的分组长度。
英文摘要：
Applying the Riemann geometric machinery of volume estimates in terms of curvature, bounds for the minimal distance of packings/codes in the Grassmann and Stiefel manifolds will be derived and analyzed. In the context of space-time block codes this leads to a monotonically increasing minimal distance lower bound as a function of the block length. This advocates large block lengths for the code design.
