摘要：
Dear editor,Orthogonal frequency division multiplexing(OFDM) has been adopted in new radio(NR) [1], and multiple-port demodulation reference signal(DMRS) has been designed to achieve channel estimation. In NR, two ports of DMRS share the same frequency resource elements(RE) by employing an orthogonal code comprising cyclic shift phase. In general, channel estimation can be achieved via the classical discrete Fourier transform(DFT) scheme [2, 3] as channels for the two ports of DMRS can be separated in the time domain via the DFT scheme.
