Special pulse-shapes such as OFDM or Nyquist signaling were utilized resulting in a highly efficient usage of the available fiber channel bandwidth. This was achieved by parallel data processing with high-end FPGAs. Furthermore, highly efficient Rx algorithms for carrier and timing recovery as well as for polarization demultiplexing were developed and investigated UR - https://www.ksp.kit.edu/9783731502579 UR - https://directory.doabooks.org/handle/20.500.12854/57679 ER -
