WebII. M-ary Modulation Signals A general chirp signal is represented by a starting frequency, a chirp rate, and a chirp duration[3]. A novel binary chirp modulation is presented in Ref.[9] where a linear function is adopted as the integral impulse for the time-varying function of phase. Now we extend the binary chirp modulation to M-ary 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

"WebGiven that a binary sequence has been generated from n ( t ), we now consider the method of chirp coding. The purpose of chirp coding is to ‘diffuse’ each bit over a range of compact support T. However, it is necessary to differentiate between 0 and 1 in the sequences. The simplest way to achieve this is to change the polarity of the chirp. " - Binary chirp signal
