چکیده

In this paper, an adaptive subcarrier assignment method based on a stable matching algorithm is considered. From the performance comparison with other assignment methods (Hungarian-algorithm-based, contiguous and interleaved), our assignment method, while of relatively low complexity, resulted in a satisfactory performance in terms of per-ONU and overall achievable throughputs, and also it responded to the traffic demands.

Application of feasible vertex labeling for dynamic capacity allocation of a multicarrier multimode PON

Multimode PON is considered as a potentially cost-effective solution for a Full Service Access Network. To avoid the limited bandwidth-distance product of multimode fiber when using baseband transmission, passband transmission which utilizes highorder transmission lobes in GHz region of the electrical-domain link frequency responses can be used instead [1]. However, due to the intermodal disper...

Resource Allocation for OFDM Systems Based On Sub-Carrier Pairing

Orthogonal Frequency Division Multiplexing (OFDM) is a form of multicarrier modulation. Different symbols are transmitted over different subcarriers. The use of relays increase the coverage area, improve spectral efficiency and also the network lifetime. On the basis of the amplify and forward relaying mode, a two hop multi relay system is proposed with joint relay selection, subcarrier assignm...

Using Higher-Order Passbands of Multimode Fibre for Subcarrier Multiplexing

The frequency response of multimode optical fibre (MMF) shows the existence of passbands in the higher frequency region above the -3dB baseband. By Subcarrier Multiplexing, these passbands can be used to accommodate a number of transmission channels for different services. In this way various groups of services may be integrated in a single MMF-based in-building or short-reach access infrastruc...

0.6Tb/s-km Multimode Fibre Feasibility-Experiment using 40-Channel DWDM over Quadrature-Subcarrier Channels

Abstract: We describe the complete implementation of a 204Gb/s throughput quadrature-subcarrier system for standard within-building 50μm multimode fibre applications. The simultaneous transmission of 40 DWDM channels, utilizing in-phase and quadrature 2.55Gb/s subcarrier signals, is shown to be feasible. Complete data and carrier synchronization was provided by a zero-latency, pilot-tone based,...
