Chirp processing correlation
WebNote that in the decoding program, the correlation process is carried out using a spatial cross-correlation scheme (using the MATLAB function xcorr), i.e. the watermark is recovered using the process chirp (t) ⊙ s(t) instead of the Fourier equivalent CHIRP*(ω)S(ω) where CHIRP and S are the Fourier transforms of chirp and s … WebChirp Data Processing Phase 1 – Correlation and Deconvolution A zero-phase correlation of the uncorrelated data was performedutilising the source sweep in Figure 1a. …
