Abstract: A reception signal demodulation device which converts a modulated reception signal into a digital signal and performs signal reconstruction includes a demodulator which demodulates the received signal, a matched filter which improves a signal-to-noise power ratio of the signal from the demodulator, a threshold value discriminator which determines a compression rate based on the signal from the matched filter, and a reconstruction circuit which compresses the signal from the matched filter, converts it into the digital signal, and performs signal reconstruction from the signal converted into the digital signal based on the compression rate.

Abstract: A control program for an information processing terminal device causes an information processing terminal device to execute: an identification information reception process for receiving mobile body identification information which has been transmitted from a mobile body, from which the mobile body is identifiable, and which indicates a state of the mobile body; and an identification information transmission process for transmitting the received mobile body identification information to a mobile body management device that manages the mobile body. Thus, it is possible to comprehensively ascertain the operational status of a large number of mobile bodies in various locations in order to accurately manage operation of the mobile bodies.
