A new two-dimensional modulation technique called Orthogonal Time Frequency Space
(OTFS) modulation designed in the delay-Doppler domain is introduced. Through this …

In this paper, we study time-varying orthogonal frequency division multiplexing (OFDM)
systems, and propose a joint channel-and-signal estimation receiver based on turbo …

Under the condition of slow fading time-varying multipath channel with low rice factor, it is
difficult to make effective use of signal energy, therefore, the traditional Minimum Mean …

In this paper, we propose a new space-frequency adaptive equalization (SFAE) method for
single carrier frequency domain equalization (SC-FDE) systems that can deal with multipath …

In this paper, we propose a novel receiver design for orthogonal frequency division
multiplexing (OFDM) transmission over doubly (time-and frequency-) spread channels …

In this paper, a simple equalization strategy for OFDM waveforms is proposed that
specifically targets the case where the cyclic prefix is insufficient to span the whole channel …
