Optimal signal subspace is the foundation for our adaptive modulation algorithms in SC-FDE. Another new concept is introduced called sequenced optimal signal subspaces.

最优信号子空间的思想是SC - FDE中设计自适应调制算法的根本基础，在此基础上又提出了序列最优信号子空间的概念。

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。
