在这篇短文中,我们提出了一个简单的两阶段稀疏相位恢复策略,该策略使用接近最优的测量数量,并且计算效率高,对测量噪声具有鲁棒性。此外,所提出的策略是相当普遍的,允许大量的新的测量结构和恢复算法的设计以最小的努力。
In this short note we propose a simple two-stage sparse phase retrieval strategy that uses a near-optimal number of measurements, and is both computationally efficient and robust to measurement noise. In addition, the proposed strategy is fairly general, allowing for a large number of new measurement constructions and recovery algorithms to be designed with minimal effort.
