Fig. 5From: Holographic detection of AIS real-time signals based on sparse representationError rate under different SNR: the error rate performances of the original algorithm and the processing time and noise resistance-improved algorithm under different SNRs. The x-axis is the number of iterations and the y-axis denotes the error rate. The SNR changes from 0 dB to 20 dB and the step is 5 dBBack to article page
