本文考虑了从调制空间中信号的幅度测量值的信号恢复问题。它提出了一个测量设置，以使该信号空间中的几乎每个信号都可以从其振幅测量值重建到全局恒定相，并且采样率是信号空间创新的四倍。计算机模拟证明了在噪声测量下提出的方案的适用性。
This paper considers the problem of signal recovery from magnitude measurements for signals in modulation invariant spaces. It proposes a measurement setup such that almost every signal in such a signal space can be reconstructed from its amplitude measurements up to a global constant phase and with a sampling rate of four times the rate of innovation of the signal space. The applicability of the proposed scheme under noise measurements is demonstrated by computer simulations.
