Real-time Digital Signal Processing for Software-defined Optical Transmitters and Receivers

By: Material type: ArticleArticleLanguage: English Publication details: KIT Scientific Publishing 2014Description: 1 electronic resource (X, 219 p. p.)ISBN:
  • KSP/1000042847
  • 9783731502579
Subject(s): Online resources: Summary: A software-defined optical Tx is designed and demonstrated generating signals with various formats and pulse-shapes in real-time. 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.
