cluster 2

Linux-Cluster for simulation of optical transmission systems and electrical receivers including equalization and decoding. Due to sophisticated programming we nearly reach 30-fold processing speed with 10 standard PCs compared to the processing power of a single PC.

field

BER performance of combined chromatic dispersion (CD) and differential group delay (DGD) distortions with equalization by a 16-state Viterbi-Algortihm and 4-bit quantization. The plot contains results for duobinary (DB,solid colored), NRZ (solid white) and CSRZ (transparent) modulation.

encoder

Various detection and equalization schemes for DQPSK modulation have been evaluated at our institute including digital clock-phase recovery.
