摘要：

在分析现有基于压缩感知的模拟信息转换器架构的基础上，对并行多支路模拟信息转换器模型进行了改进，提出了一种基于分块对角化思想的分段分块式模拟信息转换模型．该模型将等效测量矩阵转化为结构化的分块对角阵，利用各分块的相对独立性可实现存储复用，节省了硬件资源，同时减少了各支路的积分时间，能够适用于单位时间内存在大规模压缩采样值的场合．实验结果表明了此方法的有效性，与现有的分段式并行压缩采样转换器相比，其复杂度小，且具有良好的可复用性和实用性．

Abstract:

Based on the analysis of the existing analog-to-information converter (AIC) under the framework of CS, a novel model called the segmented and blocked AIC (SB-AIC) based on block diagonalization is proposed. In this model, the measurement matrix is transformed into a structured block diagonal matrix and the block storage can be reused depending on the relative independence. Besides, the integral time of each branch can be reduced, which can be applied to mass compressive sampling per unit time. Experimental results show the effectiveness of this method, with complexity lower and practicality higher compared with the parallel AIC state of art.

Key words: compressive sensing, block diagonalization, analog-to-information converter(AIC), segmented AIC
