WebSep 15, 2006 · Binary chirp slope keying (CSK) has an advantage over binary phase-shift-keying (PSK) in the Rayleigh channel, in terms of probability of error (PE) as a function of signal-to-noise ratio (SNR). Clearly, for SNR above about 14.5dB, chirp slope keying performs better than standard phase shift keying in the simulated UWA environment.
