An event-driven transmission method comprises converting at least one event to at least one corresponding pulse pair and transmitting the at least one pulse pair. In this context, a delay between each pulse pair represents a corresponding identifier with respect to the respective event or with respect to at least one corresponding object causing or experiencing the respective event.

Methods, systems, and devices for wireless communications are described. A non-coherent modulation configuration may be selected for a transmission of a set of data based on a radio frequency spectrum band used for the transmission. After selecting the non-coherent modulation configuration, the set of data may be modulated using a differential phase shift keying modulation technique. After selecting the non-coherent modulation configuration, a set of frequency-domain symbols may be generated from the set of modulated symbols using a discrete Fourier transform. The set of frequency-domain symbols may be mapped to a set of subcarriers, and a time-domain waveform may be generated from the mapped set of frequency-domain symbols, yielding a time-domain waveform. The time-domain waveform may be transmitted over the radio frequency band.

Aspects of the present application provide methods and devices for using a combined QAM and APSK modulation scheme in a hybrid modulation form in order to benefit from advantages of each respective modulation scheme. The proposed hybrid modulation scheme is less sensitive to phase noise and has lower PAPR than QAM and has very similar performance as QAM with respect to AWGN.

A weight switching unit outputs weights for modulation signals so that, on a constellation diagram in the complex plane, a position of a signal point in a communication direction corresponds to that of the modulation symbol, and the position of the signal point in a non-communication direction becomes different from that of the signal point in the communication direction. Weight applying units apply, to the modulation signals emitted from antennas, weights for each modulation symbol output from the weight switching unit.
