1. A method for wireless communication at a transmitting device, comprising:
selecting, from a group of modulation configurations, a non-coherent modulation configuration based at least in part on a radio frequency spectrum band used by the transmitting device to communicate with a receiving device;
modulating, based at least in part on the non-coherent modulation configuration, a set of data using a differential phase shift keying (DPSK) modulation to obtain a set of modulated symbols;
generating a set of frequency-domain symbols from the set of modulated symbols using a discrete Fourier transform;
transmitting, to the receiving device, an indication that a non-coherent single-carrier frequency-domain multiple access (SC-FDMA) mode has been selected for transmitting the set of data; and
transmitting, in a symbol period of the radio frequency spectrum band, a time-domain waveform obtained from the set of frequency-domain symbols.
