In this paper we explore the advantage of combining M-QAM modulations, LDPC codes, and IFDMA multi-access techniques in order to increase the capacity of the system, reduce the peak-to-average power ratio (PAPR) and to improve the BER performance. The simulation results show that our proposal provides better performance, even allowing significant reductions, of about 1 dB, in the PARP of the high-level...
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...
