我们在推广这些智能手机前进行过完备的现场测试。
We have fully conducted field tests before the rollout of smartphones.
为此，本文提出了利用信号集合划分研究过完备原子库的新方法。
To reduce this high computational complexity, a new method is proposed to deal with the over-complete dictionary based on the signal set partitioning method.
本文研究工作是基于MP分解存在计算量大、过完备原子库存储量大的问题展开的。
However, the proposed algorithm based on mp can realize high speed, at the same time, the performance of the signal decomposition is assured.
