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: The present technology relates to a signal processing apparatus and method which are able to suppress a reduction in reception sensitivity.
A reception signal is compressed so as to have a predetermined signal level or lower, and transmission data transmitted from a transmitter side and included in the reception signal compressed so as to have the signal level or lower is decoded. For example, an approximate replica signal reproducing large amplitude changes of the reception signal is generated, and the approximate replica signal is subtracted from the reception signal to compress the reception signal so as to have the signal level or lower. The present disclosure is applicable to, for example, a signal processing apparatus, a reception apparatus, a transmission/reception apparatus, a communication apparatus, an information processing apparatus, an electronic device, a computer, a program, a storage medium, a system, and so on.-

摘要: The present technology relates to an information processing device and method, a transmitting device and method, and a receiving device and method, which are capable of multiplexing transmission signals in the same channel. In the present technology, 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, in the present technology, 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. The present disclosure can be applied to, for example, a transmitting device, a receiving device, a transceiving device, a communication device, an information processing device, an electronic device, a computer, a program, a storage medium, a system, and the like.

摘要: This technique relates to a transmitting apparatus and a transmission method, a receiving apparatus and a reception method, and programs that each enable securing of excellent communication quality in information transmission using an LDPC code.
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.
