WebDec 7, 2024 · Importantly, it has been shown that the waveforms in [8], [10] can be represented as DFT-s-OFDM with a unitary frequency domain chirp filter. This is a big advantage since DFT-s-OFDM is already ... A chirp pulse, however generated, can be considered as the output of one of a pair of filters, which have dispersive characteristics. So, if the transmit filter has a group delay response which increases with frequency, then the receive filter will have one which decreases with frequency and vice versa. In principle, the transmitted pulses can be generated by applying impulses to the input of the dis…
