“…To the best of our knowledge, there are no studies focusing on UFMC system channel estimation based on time‐domain TS. The spectrum efficiency of the TFT‐UFMC and DPN‐UFMC schemes can be obtained by referring to the TFT‐ODFM [10] and DPN‐OFDM schemes [17]. Table 1 gives a comparison of the spectrum efficiency of the TFT‐UFMC, DPN‐UFMC, and proposed schemes.…”

“…The reconstruction PN sequences can be expressed as follows:

{\overset{⌢}{d}}_{i}^{n} = ({, \begin{matrix} r_{i}^{n} - y_{i - 1}^{n + N + L_{f}} & 0 \leq n < L - 1 \\ r_{i}^{n} & L - 1 \leq n < M \\ r_{i}^{n} - x_{i}^{n - M} & M \leq n < M + L - 1 \end{matrix})

From the above analyses, it can be seen that the mutual interference between the received PN sequence and the UFMC data block makes the channel estimation in the time‐domain and the frequency‐domain channel detect mutual conditions. Iterative interference cancellation detection algorithms and dual pseudo noise‐padded methods have been applied for channel estimation in some studies [16, 17]. However, the channel estimation result may not be accurate because of aliasing PN sequences.…”
