This class handles the SNR to BlcER traces. A path to a repository containing trace files should be provided. If no repository is provided the traces form default-traces.h will be loaded. A valid repository should contain 7 files, one for each modulation and coding scheme. The names of the files should respect the following format: modulation0.txt for modulation 0, modulation1.txt for modulation 1 and so on... The files format should be as follows SNR_value(1) BER(1) Blc_ER(1) STANDARD_DEVIATION(1) CONFIDENCE_INTERVAL1(1) CONFIDENCE_INTERVAL2(1) SNR_value(2) BER(2) Blc_ER(2) STANDARD_DEVIATION(2) CONFIDENCE_INTERVAL1(2) CONFIDENCE_INTERVAL2(2) ... ... ... ... ... ... ... ... ... ... ... ...
