The sparse signal acts as an excitation term of a continuous-time chaotic system and the compressive measurements are performed by sampling chaotic system outputs. The reconstruction is realized through the estimation of the sparse coefficients by the principle of chaotic parameter estimation. With the deterministic formulation, the analysis on the reconstructability is conducted via the sensitivity matrix from the parameter identifiability of chaotic systems. For the sparsity-regularized nonlinear least squares estimation, it is shown that the sparse signal is locally reconstructable if the columns of the sparsity-regularized sensitivity matrix are linearly independent. A Lorenz system excited by the sparse multitone signal is taken as an example to illustrate the principle and the performance. <\/jats:p>","DOI":"10.1142\/s0218127413501988","type":"journal-article","created":{"date-parts":[[2014,1,7]],"date-time":"2014-01-07T07:29:22Z","timestamp":1389079762000},"page":"1350198","source":"Crossref","is-referenced-by-count":3,"title":["CHAOTIC ANALOG-TO-INFORMATION CONVERSION: PRINCIPLE AND RECONSTRUCTABILITY WITH PARAMETER IDENTIFIABILITY"],"prefix":"10.1142","volume":"23","author":[{"given":"FENG","family":"XI","sequence":"first","affiliation":[{"name":"Department of Electronic Engineering, Nanjing University of Science and Technology, Nanjing, Jiangsu 210094, P.
