Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 25:
26. An apparatus for wireless communication at a receiving device, comprising:
a processor,
memory coupled with the processor; and
instructions stored in the memory and executable by the processor to cause the apparatus to:
select, 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 receiving device to communicate with a transmitting device;
receive, from the transmitting device, an indication that a non-coherent single-carrier frequency-domain multiple access (SC-FDMA) mode has been selected for transmitting a set of data;
receive, in a symbol period of the radio frequency spectrum band, a time-domain waveform;
generate a set of frequency-domain symbols from the time-domain waveform using a discrete Fourier transform;
demap the set of frequency-domain symbols from a set of subcarriers in the radio frequency spectrum band;
generate a set of modulated symbols from the demapped set of frequency-domain symbols using an inverse discrete Fourier transform; and
demodulate, based at least in part on the non-coherent modulation configuration, the set of modulated symbols using a differential phase shift keying (DPSK) demodulation to obtain the set of data.
