    Abstract: A precoding process is performed on a first baseband signal and a second baseband signal to generate a first precoding signal and a second precoding signal. A pilot signal is inserted into the first precoding signal and phase change is performed on the second precoding signal. A pilot signal is inserted into the phase changed second precoding signal, and phase change is further performed on the phase-changed second precoding signal with the pilot signal inserted.

    Abstract: A three-dimensional data encoding method is a three-dimensional data encoding method of encoding a plurality of three-dimensional points, and includes: selecting one prediction mode for calculating, using attribute information of a second three-dimensional point in a vicinity of a first three-dimensional point, a predicted value of attribute information of the first three-dimensional point; calculating a predicted value according to the one prediction mode; calculating a prediction residual that is a difference between the attribute information of the first three-dimensional point and the predicted value; and generating a bitstream that includes the one prediction mode and the prediction residual, and in the calculating of the predicted value, a predetermined fixed value is calculated as a predicted value calculated according to the one prediction mode in a case in which a predicted value based on the attribute information of the second three-dimensional point is not assigned to the one prediction mode.

    Abstract: A transmission device includes: a weighting synthesizer that generates a first precoded signal and a second precoded signal from a first baseband signal and a second baseband signal, respectively; a phase changer that applies a phase change of i×Δλ to the second precoded signal; an inserter that inserts a pilot signal into the second precoded signal applied with the phase change; and a phase changer that applies a phase change to the second precoded signal applied with the phase change and inserted with the pilot signal. The weighting synthesizer performs, in the precoding process, a calculation that uses F = ( e j ⁢ ⁢ θ 11 e j ⁡ ( θ 11 + π 4 ) e j ⁢ ⁢ θ 21 e j ⁡ ( θ 21 + π + π 4 ) ) on the first baseband signal and the second baseband signal modulated via a modulation scheme of QPSK.

    Abstract: An information transaction method of the present disclosure includes an information providing phase of providing, by an information provider, information requested by an information user via a distributed ledger of authentication server devices. In the information providing phase, an information provider terminal acquires first transaction data including an information user ID, an information provider ID, and a second information index indicating an index of first information requested by the information user among information items indicated by the first information index published in the distributed ledger, the first transaction data being written in the distributed ledger. The information provider terminal generates first encrypted information by encrypting the first information designated by the second information index, generates second transaction data including the information provider ID, the information user ID, and the first encrypted information, and transmits the second transaction data to an authentication server device.
