Data in the Excel file firstly compares the optical back-to-back performance of 20Gb/s single carrier DDQPSK system using different types of filters as well as the transmission performance of the 144-Gp/s Nyquist-DDQPSK system.
Data in the CSV file gives the back-to-back signal spectra after balanced photodetector at different frequency offsets, as depicted in Fig. 3 (b) in the paper. This csv file is very large and should be opened with Matlab to avoid omission. Column A ,C and E are x axis and denote frequency in GHz with column B, D and F corresponding to the power in dBm. Pair (A,B) , (C,D) and (E,F) are respectively for the spectrum at frequency offset of -2 GHz, 0 GHz and 2 GHz.
