WebThis paper proposes a new idea to design a waveform sequence starting from a reduced number of distinct cyclically shifted chirps by exploiting the Eulerian circuit. For a given number of distinct waveforms, the set of optimum shifts of the cyclically shifted chirps are provided as normalized values that can be used for any pulse width. WebThis paper investigates a novel design for joint radar-communication (JRC) waveform, which is capable of improving the network’s performance by solving the phase shift mutation of the Chirp-BPSK …
