Abstract
The disclosure relates to a signal processing device and method, and an information processing device and method, in which a distance between a position where a signal is transmitted and a position where the signal is received can be obtained with higher accuracy. A predetermined signal is transmitted as a radio signal at a predetermined timing known to a receiving side. Additionally, a propagation delay amount, which is a delay amount from a transmission timing to a reception timing of a predetermined signal received as a radio signal, is calculated on the basis of a correlation between the signal and a reference signal synchronized with the transmission timing. Furthermore, the distance between the position where a predetermined signal is transmitted and the position where the signal is received is calculated on the basis of a propagation delay amount of the signal.
