Chirp-Slope Keying (CSK) is a new and innovative digital modulation scheme forunderwater data transmission. The underwater environment brings up severalchallenges to the manufacturing and operation of communication systems. This thesisshows through analysis and simulations the effectiveness of Chirp-Slope Keying (CSK)in providing a satisfying performance in underwater communication. The experimentconsists of modulating a chirp slope by binary numbers (representing our data). ?0? isrepresented by a linear- down chirp and ?1? is represented by a linear-up chirp . Thereceived data is first processed by a correlator receiver. Then, the detection of eitherbinary symbol is obtained by the comparison to a threshold. Simulation results fornumerous signal-to-noise ratios show that CSK provides satisfying performance forunderwater data transmission.
The Mississippi gulf coast shallow water Data collected from the NationalOceanic and Atmospheric Administration (NOAA), (see appendix), allow us toaccurately generate a laboratory model for the channel of interest.
