Abstract: A method for designing pilots inserted into orthogonal frequency division multiplexing (OFDM) waveform intended for channel estimation such that the channel can be seen and estimated in both time-frequency and delay-Doppler domains. The ability of estimating the sparsest channel impulse response will provide environment mapping and therefore sensing.
