从结构偏置测量中恢复二进制稀疏信号

Recovery of Binary Sparse Signals from Structured Biased Measurements

Sandra Keiper

摘要:

本文研究了由部分随机循环测量重构二进制稀疏信号的问题。我们表明,通过最小二乘算法的重建是一样好的重建,通过通常使用的程序基追求。我们进一步表明,我们需要尽可能多的测量,以恢复一个$s$ -稀疏信号$x_0\in\mathbb{R}^N$,因为我们需要恢复一个密集的信号,更准确地说,一个$N-s$ -稀疏信号$x_0\in\mathbb{R}^N$。我们进一步建立稳定的噪声测量。

英文摘要:

In this paper we study the reconstruction of binary sparse signals from partial random circulant measurements. We show that the reconstruction via the least-squares algorithm is as good as the reconstruction via the usually used program basis pursuit. We further show that we need as many measurements to recover an $s$-sparse signal $x_0\in\mathbb{R}^N$ as we need to recover a dense signal, more-precisely an $N-s$-sparse signal $x_0\in\mathbb{R}^N$. We further establish stability with respect to noisy measurements.
