This algorithm has higher spectral efficiency compared with present one. According to the character of sequenced optimal signal space in SC-FDE, we propose an algorithm called minimum power algorithm.

论文依据贪婪算法提出了SC-FDE中的最小功率算法，该算法需要回传信息量小，计算复杂度比较低。

Not this time. The Jackson memorial may signal that Los Angeles' civic space, instead of expanding as once promised, is just withering away.

但不是现在，杰克逊的悼念活动标志着洛杉矶民众的空间并不像承诺的那样逐渐扩大，相反是缩小了。
