OFDM-based Waveforms for Joint Sensing and Communications Robust to Frequency Selective IQ Imbalance
Oliver Lang, Christian Hofbauer, Moritz Tockner +3
Orthogonal frequency-division multiplexing (OFDM) is a promising waveform candidate for future joint sensing and communication systems. It is well known that the OFDM waveform is v…
