Actual correlation and SWC of one node pair (100SN for 100 TRs window) before addition of the noise in (a) and after addition of additive white Gaussian noise (AWGN) with an SNR of 20 dB in (b) and 10 dB in (c). Noise reduces the sharp transitions of the SWC results. The identification of transition points becomes more difficult for small SNR (c) compared with large SNR (b).
