Chirp slope keying
WebOct 3, 2024 · The general expression for the basic chirp, ignoring the amplitude, phase and frequency, is written as x(t) = ej ( πμt2 + 2πft + θ) The factor π is actually 2π scaled by 1 / 2. This is included to normalize the chirp rate as the slope of the instantaneous frequency which is defined as the derivative of the argument. WebJan 28, 2024 · In Frequency Shift Keying the transmitted signal shifts between two different frequencies to represent binary data, like two different notes from a piano. This would technically be 2-FSK...

WebA chirpis a signalin which the frequencyincreases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirpis used interchangeably with sweep signal.[1] It is commonly applied to sonar, radar, and lasersystems, and to other applications, such as in spread-spectrumcommunications (see chirp spread spectrum). http://ijceng.com/gallery/9-cej-2760.f.pdf
WebOct 17, 2024 · Chirp Slope Keying (CSK) is a simple and robust broadband modulation scheme for practical Underwater Wireless Acoustic (UWA) communications at relatively low data rates where information is modulated in the slope of a chirp signal. In this paper, we have compared the performance of JANUS and CSK using channel replay simulation.
