Abstract
Methods, systems, and devices for wireless communications are described. A transmitting device may generate a first time-domain reference signal sequence of a first sequence length, and may truncate the first sequence length to a second sequence length and may append a header portion and a tail portion to the truncated first time-domain reference signal sequence. The transmitting device may perform a discrete Fourier transform (DFT) on the truncated first time-domain reference signal sequence to generate a frequency-domain reference signal sequence associated with a phase constant, and may perform an inverse fast-Fourier transform (IFFT) on the result of the DFT. The transmitting device may then transmit the result of the IFFT to a receiving device, which may further process the signal by performing a fast-Fourier transform (FFT), dividing by the phase constant, and taking the conjugate of the received sequence.
