energy-efficient ICI cancellation technique for bandwidth improvements through cyclic prefix reuse in an OFDM Article

Sandeep SAROWA, Harmanjeet SINGH, Sunil AGRAWAL, B. S. SOHI

Frontiers of Information Technology & Electronic Engineering 2017, Volume 18, Issue 11,   Pages 1892-1899 doi: 10.1631/FITEE.1601333

Abstract: Orthogonal frequency division multiplexing (OFDM), a very promising technique that is leading the evolutionbandwidth scarcity issue in spectrum allocation, is severely affected by the undesirable effects of the frequencyerror, which generates inter carrier interference (ICI) due to the Doppler shift and local oscillator frequencyUnlike SC and MLE where the whole OFDM symbol data is transmitted in duplicate to create redundancy at

A Multi-wavelength Star Optical Network Reusing All Channel Wavelengths Three Times and Its Features

Gan Chaoqin

Strategic Study of CAE 2002, Volume 4, Issue 10,   Pages 84-89

Abstract:

In this paper, a novel multi-wavelength star optical network reusing all channel wavelengths three times is proposed by the method of “（Distributed Architecture) + (Return Link) + (Wavelength Group)”. In this scheme, by interconnecting four conventional star couplers and reusing all channel wavelengths three times, both the maximum number of supportable nodes and the maximum throughput of the network are all up to four times as many as that of conventional WDM star network. Utilizing bidirectional transmissions in a single fiber, half fibers can be saved under the same number of supportable nodes. Making use of the distributed architecture, the anti-destructibility of network is drastically raised. All these advantages of the network efficiently overcome the disadvantages of conventional WDM star network.
