Non-coherent waveforms for wireless communication

An apparatus configured for wireless communication, the apparatus comprising:

• at least one processor;
• and
• a memory coupled to the processor, the processor is configured:
• to perform, by a wireless communication device, a non-coherent encoding operation on first data to generate a first transmission, wherein the non-coherent encoding operation encodes data independent of channel state information (CSI) using a non-coherent differential modulation encoding scheme in a frequency domain for adjacent subcarriers in an orthogonal frequency-division multiplexing (OFDM) waveform;
• and
• to transmit, by the wireless communication device, the first transmission, wherein the first transmission is non-coherently encoded and corresponds to a millimeter wave transmission, and wherein the first data is encoded in phase difference between two consecutive resource elements (REs) in the frequency domain.
