摘要： The present disclosure relates to a transmission apparatus, a transmission method, a reception apparatus, and a reception method that can ensure a reduced processing burden on a receiving side in LPWA (Low Power Wide Area) communication.
Communication data is sent and received at a communication time of day and a communication frequency based on group identification information set for groups into which a plurality of transmission apparatuses is divided and communication interval information shared by the transmission apparatuses and a reception apparatus, rather than individual identification information. The present disclosure is applicable to an LPWA communication system.-

摘要： An object of the present invention is to secure a relative relationship when positions are displayed by use of position information transmitted from a plurality of wireless communication devices. Each of the wireless communication devices of the present invention includes a position information acquisition unit and a transmission unit. The position information acquisition unit acquires the position information of the wireless communication devices by the GPS, for example. At that time, the position information acquisition unit also acquires time information when the position information is acquired. The transmission unit transmits transmission data including the position information and the time information when the position information is acquired in a predetermined transmission slot.

摘要： An information processing device and method, a transmitting device and method, and a receiving device and method are disclosed for multiplexing transmission signals in the same channel. In one example, transmission signals are generated by performing chirp modulation on data to be transmitted, and the transmission signals are multiplexed by shifting transmission timings of a plurality of transmission signals in a time direction and transmitting the transmission signals. Further, a plurality of chirp-modulated transmission signals which are multiplexed by shifting the transmission timing in the time direction and transmitted from a transmission side are received, and the plurality of received transmission signals are dechirped at timings according to the transmission timings.

摘要： The present technology relates to an information processing device, an information processing method, a transmitter, a transmission method, a receiver, and a reception method which can provide setting information necessary for each receiver. An information processing device of one aspect of the present technology holds non-common setting information that is not common setting information among setting information used in transmitters for setting for transmitting information in association with identification information of the respective transmitters. In addition, the information processing device transmits, to a receiver that has received identification information transmitted from a predetermined transmitter using common setting information that is setting information common in the plurality of transmitters, the non-common setting information associated with the identification information received by the receiver. The present technology can be applied, for example, to a communication system in which data is transmitted from a transmitter to a receiver through unidirectional communication.

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.
