- extended unitary group 广义酉群
- With the increase of the code rate, the production distance between the constellation of the unitary group code decreases rapidly and deteriorates the performance of the system. 随着码率的不断增加,酉空时码群中的各个星座点之间的乘积距离会变得越来越小,从而导致性能恶化。
- An analytical treatment fsr a Strong Crystal field in an Octahedral Symmetry by using the unitary group approach is given. It Shows that the convenience of the Unitary group opproach is comparable with that of the Racah method. 应用酉群方法对强晶体场的八面体对称问题进行解析处理,表明酉群方法和Racah方法同样有效。
