摘要： In a transmission method according to one aspect of the present disclosure, a encoder performs error correction coding on an information bit string to generate a code word. A mapper modulates a first bit string in which the number of bits is the predetermined integral multiple of (X+Y) in the code word using a first scheme, the first scheme being a set of a modulation scheme in which an X-bit bit string is mapped to generate a first complex signal and a modulation scheme in which a Y-bit bit string is mapped to generate a second complex signal, and modulates a second bit string in which the first bit string is removed from the code word using a second scheme different from the first scheme.

摘要： Various example embodiments provide a system for transmission of low power signals based on using transmission time as one coding parameter. A code table may be used at a transmitter and receiver to map different data to different transmission times and/or other parameters. Advantageously, large amount of information may be transmitted with short and power efficient signals, for example to report status of a sensor every now and then. A receiver may use the same code table to decode the signals. Apparatuses, methods, and computer programs are disclosed.
