WebChirp Slope Keying: A Practical Benchmark Modulation Scheme for Underwater Acoustic Channel Replay Simulation Abstract: Performance bench-marking of underwater … Webshows through analysis and simulations the effectiveness of Chirp-Slope Keying (CSK) in providing a satisfying performance in underwater communication. The experiment consists of modulating a chirp slope by binary numbers (representing our data). „0‟ is represented by a linear- down chirp and „1‟ is represented by a linear-up chirp .

WebThe idea to use chirps for modulating a signal, e.g., as Chirp Slope Keying (CSK) is often attributed to Winkler et al.’s work in the early 1960s [ 29 ], and also sometimes referred … WebChirp Slope Keying (CSK) is a digital chirp modulation scheme in which binary data are represented using chirps of increasing and decreasing frequencies versus time. In other wo rds, an up chirp represents a 1 while a down chirp represents a 0.
WebDec 24, 2003 · Our design focused on bandwidth efficiency while maintaining good synchronization performance and low complexity.

In its simplest form, the binary information modulates the slope of a linear chirp, with up-chirps representing ones and down-chirps representing zeros. A time …
WebAs a spread-spectrum system, chirp slope keying (CSK) uti-lizes a data-modulated signal with its energy spread over a bandwidth that is much greater than the rate of information be-ing transmitted. Chirp slope keying Chirp signals in digital communications were apparently origi-nally suggested by M. R. Winkler. 3. in 1962and then abandoned.
