压缩感知(CS)文献表明，从独立随机分布中提取元素的感知矩阵具有增强的重构能力。在许多CS应用中，如电磁成像，测量系统的实际限制阻止人们以这种方式产生传感矩阵。虽然人们通常可以在一定程度上随机化测量值，但这些感知矩阵并不能获得与真正随机化感知矩阵相同的重构性能。本文提出了一种基于容量最大化的感知矩阵设计方法，该方法具有增强的块稀疏信号重构能力。通过几个数值例子，我们证明了我们的方法是如何显著提高重建性能的。

英文摘要：
  It is well established in the compressive sensing (CS) literature that sensing matrices whose elements are drawn from independent random distributions exhibit enhanced reconstruction capabilities. In many CS applications, such as electromagnetic imaging, practical limitations on the measurement system prevent one from generating sensing matrices in this fashion. Although one can usually randomized the measurements to some degree, these sensing matrices do not achieve the same reconstruction performance as the truly randomized sensing matrices. In this paper, we present a novel method, based upon capacity maximization, for designing sensing matrices with enhanced block-sparse signal reconstruction capabilities. Through several numerical examples, we demonstrate how our method significantly enhances reconstruction performance.
