Long-Range Acoustic Communication Using Differential Chirp Spread Spectrum

Long-Range Acoustic Communication Using Differential Chirp Spread Spectrum

Here, we propose a new modulation method using chirp spread spectrum (CSS) modulation to indicate the result of long-range acoustic communication (LRAC). CSS modulation had outstanding matched filter characteristics even though the channel was complex. The performance of the matched filter depends o...
