A communication device comprising: a wireless communication section configured to wirelessly receive a signal from another communication device; and a control section configured to estimate a reception time of the second signal based on the expanded signal matrix that minimizes the predetermined norm, wherein the control section executes the iterative calculation separately at a plurality of stages, sets a value of the regularization parameter used for the iterative calculation at or after a second stage of the plurality of stages to a value of the regularization parameter or more used for the iterative calculation at a previous stage, and changes the value of the regularization parameter based on a reception status of the second signal during the iterative calculation at or after the second stage.

Communication device, information processing method, and non-transitory computer-readable storage medium

A control device comprising: a control unit that applies a weight parameter based on a reliability parameter that is an index indicating a degree of whether or not a signal is appropriate as a processing target for estimating a positional relationship between the communication device and the other communication device calculated on the basis of a signal received from the other communication device by the communication device to a provisional positional relationship between at least two of the communication devices and the other communication device estimated on the basis of the signals transmitted and received between the communication device and the other communication device, and performs control for estimating the positional relationship between the communication device and the other communication device.

Control device, system, and control method

To estimate a positional relationship between devices having transmitted and received signals with higher accuracy. A control device includes a control unit that compares reliability parameters that are indexes indicating a degree of whether or not a signal is appropriate as a processing target for estimating a positional relationship between each of the plurality of communication devices and the other communication device, calculated on the basis of the signals received from the other communication device by the communication device, and performs control for estimating the positional relationship on the basis of a signal transmitted and received between the communication device that has received a signal that is more appropriate as a processing target for estimating the positional relationship and the other communication device.

To estimate a positional relationship between devices having transmitted and received signals with higher accuracy. A control device comprising:

To provide a novel and improved control device and storage medium capable of performing control based on a positional relation with higher accuracy. A control device includes a control unit configured to perform control based on a presence area of a first communication device determined using a signal transmitted and received between the first communication device and at least one second communication device. The control unit performs control related to an operation of a controlled device in accordance with a second presence area when a first presence area determined based on a coordinate position of the first communication device on an arbitrary coordinate system associating the first communication device with the second communication device is inconsistent with the second presence area determined based on a distance between the first and second communication devices.

Control device and storage medium

To provide a novel and improved control device and storage medium capable of performing control based on a positional relation with higher accuracy. A control device includes a control unit configured to perform control based on a presence area of a second communication device estimated using signals transmitted and received between a first communication device and the second communication device. The control unit performs control based on a presence area estimated most often among a plurality of presence areas estimated from signals transmitted and received a plurality of times during a certain time length.
