Capacity achieving nonbinary LDPC coded non-uniform shaping modulation for adaptive optical communications.
A mutual information inspired nonbinary coded modulation design with non-uniform shaping is proposed. Instead of traditional power of two signal constellation sizes, we design 5-QAM, 7-QAM and 9-QAM constellations, which can be used in adaptive optical networks. The non-uniform shaping and LDPC code rate are jointly considered in the design, which results in a better performance scheme for the ...
متن کاملAdvanced GF(3) nonbinary LDPC coded modulation with non-uniform 9-QAM outperforming star 8-QAM
In this paper, we first describe a 9-symbol non-uniform signaling scheme based on Huffman code, in which different symbols are transmitted with different probabilities. By using the Huffman procedure, prefix code is designed to approach the optimal performance. Then, we introduce an algorithm to determine the optimal signal constellation sets for our proposed non-uniform scheme with the criteri...
متن کاملEvaluation of four-dimensional nonbinary LDPC-coded modulation for next-generation long-haul optical transport networks.
Leveraging the advanced coherent optical communication technologies, this paper explores the feasibility of using four-dimensional (4D) nonbinary LDPC-coded modulation (4D-NB-LDPC-CM) schemes for long-haul transmission in future optical transport networks. In contrast to our previous works on 4D-NB-LDPC-CM which considered amplified spontaneous emission (ASE) noise as the dominant impairment, t...
متن کاملAdaptive Modulation for LDPC coded-OFDM based Powerline communication system
As a result of the impairments generated by the consumer electronic devices on power line channel extensive research has been carried out to mitigate the deteriorating effects. In this work the performance of an OFDM based power line communication system is evaluated under OPERA [1] proposed power line channel. An adaptive modulation system is designed and the performance advantages of the syst...
متن کاملCoded Modulation Techniques in Fiber-Optical Communications
Today’s high demand for increasing the data transmission rate motivates a great challenge to improve the spectral efficiency of fiber-optical channels. In order to achieve a higher spectral efficiency, exploiting an advanced coded modulation scheme is inevitable. Since a general fiber-optic link is a non-Gaussian channel with nonlinear behavior, new coded modulation schemes need to be designed ...
