M-ary nonlinear sine chirp spread spectrum for underwater acoustic communication based on virtual time-reversal mirror method
Abstract Linear chirp spread spectrum technique is widely used in underwater acoustic communication because of their resilience to high multipath and Doppler shift. Linear frequency modulated signal requires a high spreading factor to nearly reach orthogonality between two pairs of signals. On the o...
