Abstract:
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 including 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.

Claim (Index 9):
An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform:\n receiving, over a channel, a signal modulated according to zero-tail discrete Fourier transform spread orthogonal frequency division multiplexing (ZT DFT-s-OFDM); down-sampling the signal into a first sequence comprising N samples; removing first Nh samples and last Nt samples from the first sequence, thereby obtaining a second sequence having a length of N-Nh-Nt; correlating the second sequence with a reference sequence which has a length N-Nh-Nt; and estimating a frequency response of the channel based on a result of the correlation.
