1. A method for wireless communication at a wireless device, comprising:
generating a plurality of symbols, wherein each symbol of the plurality of symbols comprises a first portion comprising data and a second portion comprising a demodulation reference signal (DMRS) sequence, wherein the second portion of each symbol is positioned at the end of the respective symbol;
adding, to a beginning of each symbol in the plurality of symbols, a cyclic prefix comprising a repetition of the DMRS sequence in the second portion of the respective symbol; and
transmitting the plurality of symbols, including the cyclic prefix at the beginning of each respective symbol, in a burst over a wireless channel using a single-carrier waveform.
