Webwhere M is the polynomial order ( M =2 for chirp signal), 0 n N 1,N is the signal length and is the sampling interval. The principle of DPT is as follow. When DPT is applied to a mono-component signal with polynomial phase of order M , it produces a spectral line [1] . The position of this spectral line at frequency 0 provides an estimate of the Webchirp rates, for binary signalling. Chirp spread spectrum is a spread spectrum technique that uses wideband linear frequency modulated chirp pulses to encode information. A chirp is a sinusoidal signal whose frequency increases or decreases over a certain amount of time [7]. Theoretically, chirp modulation is
