LDPC-DWDM processing for Optical communications using polymer fiber

In this paper, it show a proposal using the combining the LDPC codes whit the DWDM on Optical Transmission, where tree messages are send by an optical channel. The messages are codified whit LDPC codes and modulated whit BPSK before to transmit over the plastic optical fiber, the channel is affected by the characteristic attenuation of the POF-PMMA is show in the System Description Section. The result of this simulation realized in the Matlab software present graph results as the spectral power received and the Bit Error Rate (BER) in 50 meters of plastic optical fiber.
