title = "UW-CTSM: Circular Time Shift Modulation for Underwater Acoustic Communications",
abstract = "Pulse Position Modulation (PPM) has shown great advantages by being non-coherently implementable. However, PPM suffers from the high multipath delay in underwater acoustic channels. To be robust against the effects of multipath delay and additive noise in underwater acoustic communications, this project proposes a novel modulation scheme that is nonlinear and that can be implemented non-coherently, called the Circular Time Shift Modulation (CTSM) based on the high autocorrelation property of Zero-Correlation-Zone (ZCZ) signals. The performance of CTSM in terms of bit error rate is investigated by emulations based on real underwater acoustic channels collected in the Gulf of La Spezia, Italy, using the Littoral Ocean Observatory Network (LOON) testbed hosted at the NATO Centre for Maritime Research and Experimentation (CMRE) in June 2021. The results have shown that the CTSM system has higher robustness compared with PPM in underwater acoustic communications. ",
