DFT‐based channel estimation refinement by clustering in FBMC‐OQAM system
The Journal of Engineering, Volume 2019, Issue 3, Page 652-656, March 2019., 2019 The conventional DFT‐based channel estimation method can improve the performance of the least square (LS) or minimum mean square error (MMSE) channel estimation by removing the noise outside the maximum channel delay while the noise inside channel delay still remain.

A Novel Signal Detection Algorithm for Underwater MIMO‐OFDM Systems Based on Generalized MMSE
Journal of Sensors, Volume 2019, Issue 1, 2019., 2019 The MIMO‐OFDM system fully exploits the advantages of MIMO and OFDM, effectively resisting the channel multipath fading and inter‐symbol interference while increasing the data transmission rate. Studies show that it is the principal technical mean for building underwater acoustic networks (UANs) of high performance.
