摘要： LDPC coding is executed using a check matrix of an LDPC code whose code length is 736 bits and whose code rate is 1/4, and modulation is executed using a repetition unit that has an LDPC code obtained by the LDPC coding, repeatedly arranged therein. The LDPC code includes information bits and parity bits, the check matrix includes an information matrix portion corresponding to the information bits and a parity matrix portion corresponding to the parity bits, the parity matrix portion has a stepwise structure, the information matrix portion is indicated by a check matrix initial value table, and the check matrix initial value table is a predetermined table indicating positions of elements of “1” of the information matrix portion for each eight columns. This technique is applicable to, for example, information transmission using the LDPC code.

摘要： 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.

摘要： The present technology relates to a transmission device, a transmission method, a reception device, a reception method, and a communication method capable of shortening a pause time of data transmission.
According to an aspect of the present technology, a transmission device classifies channels usable for data transmission into a plurality of groups, selects the channels that are used in transmission units and that continue on a time axis from the channels of the different groups in accordance with an identifier, and performs the data transmission of the transmission units by using the selected channels. It is possible to make application to a communication system transmitting data through one-way communication from a transmission device to a reception device.-

摘要： By switching the transmission mode according to the power amount of a power storage unit in a wireless communication terminal, appropriate communication performance is ensured. A communication unit transmits a packet. A comparison unit compares the power amount of the power storage unit with a predetermined threshold. A control unit causes the communication unit to transmit first transmission data in a first transmission mode in a case where the power amount of the power storage unit is larger than a predetermined threshold. Furthermore, the control unit causes the communication unit to transmit second transmission data including a known payload in a second transmission mode in a case where the power amount of the power storage unit is not larger than the predetermined threshold.
