WebMay 1, 2024 · The sine chirp is used in this paper, for which the pair of chirp is orthogonal at low SF. In Fig. 6, the time–frequency graph of 8-ary sine chirp at four different frequency bands is shown. When the symbol to be transmitted is “000”, the sine chirp in the first frequency band with a positive gradient is transmitted similarly.
