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. http://www.ece.northwestern.edu/local-apps/matlabhelp/toolbox/signal/chirp.html dataro software

A chirp pulse, however generated, can be considered as the output of one of a pair of filters, which have dispersive characteristics. So, if the transmit filter has a group delay response which increases with frequency, then the receive filter will have one which decreases with frequency and vice versa. In principle, the transmitted pulses can be generated by applying impulses to the input of the dis… Webverb (used without object) to make a characteristic short, sharp sound, as small birds and certain insects. to make any similar sound: The children chirped with amusement. verb … WebMay 1, 2000 · Historically, chirp technology has been used in military communications for many years as a spread spectrum method.
