Download or read book Real-time Digital Signal Processing for Software-defined Optical Transmitters and Receivers written by Schmogrow, Rene Marcel and published by KIT Scientific Publishing. This book was released on 2014-11-21 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
