Refresh the page, … WebFeb 1, 2024 · The idea of chirp modulation is very simple: binary data is transmitted by mapping the bits into up-chirps and down-chirps. For instance, over one bit period ‘1’ is assigned a chirp with positive rate k and ‘0’ a chirp with negative rate − k. In chirp modulation, only one bit is transmitted on one LFM chirp signal. sole proprietorship with employees
