N2 - A signal modulated according to zero-tail discrete Fourier transform spread orthogonal frequency division multiplexing (ZT DFT-s-OFDM) is received over a channel. The signal is down-sampled into a first sequence comprising N samples, N corresponding to the number of used subcarriers. The first Nh samples and the last Nt samples are removed from the first sequence, thereby obtaining a second sequence having a length of N-Nh-Nt. The second sequence is correlated with a reference sequence which has a length N-Nh-Nt, and a frequency response of the channel is estimated over the N used subcarriers based on a result of the correlation.
