“…This assumption will generally not hold true in time-varying channels, especially in fast time-varying cases. In light of the above analysis and considering that BEM based channel estimation method [13,14] can accurately estimate the time-varying channel coefficients of an OFDM symbol, we propose to combine BEM based channel estimation with WF to deal with channel estimation in time-varying channels. …”

“…First of all, we can assume exact knowledge of the FIR-BEM coefficients of the doubly-selective channel to design the FIR-BEM coefficients of the SLE/SDFE, as done in [1]- [3], which is of course not very realistic. In practice, we can use training-based [9], blind [10], or even a combination of both, labeled semi-blind, channel estimation to estimate the FIR-BEM coefficients of the doubly-selective channel, which can then be used to design the FIR-BEM coefficients of the SLE/SDFE. However, we can also avoid this intermediate channel estimation step and directly design the FIR-BEM coefficients of the SLE/SDFE in a training-based, blind, or semi-blind fashion.…”
