Abstract: A measurement signal processing unit includes a reception part that receives a compression signal y obtained by using an observation matrix Φ from a time-series detection signal of a measurement target, and a reconstruction part that reconstructs the received compression signal y. The reconstruction part includes the observation matrix Φ and a dictionary matrix Ψ including a past signal of the measurement target, obtains an estimation vector {circumflex over ( )}s by inputting the compression signal y and a sensing matrix θ to a reconstruction algorithm execution module, and derives a reconstruction signal {circumflex over ( )}x corresponding to a detection signal x by inputting, to a calculation module for obtaining a product, the obtained estimation vector {circumflex over ( )}s and the dictionary matrix Ψ.
