equivalent lowpass signal of a bandpass signal is the complex envelope of that signal:
s(t)=a(t)*cos(wt+p(t))
complex envelope of s(t)= a(t)*exp(j*p(t))
chirp signal?
The chirp signal is one of the important signaling in radar for pulse compression. In LFM chirp, we have frequency modulation which the frequency of transmitted signal changes with time.
mismatched filter matlab
Match filter gives maximum peak signal power to noise power. Design of match filter in the case of white noise and color noise and its equations is available in many textbooks. If we get far from this design, we have not best SNR. This filter called mismatch filter. For...
