Investigate spectrum-sliced WDM System for FTTH
(Springer-Verlag Berlin Heidelberg, 2011-06-27)
In this paper, we have investigated the performance of spectrumsliced WDM system for FTTH network using NRZ modulation format with 2.5 Gb/s bit rates and 0.4-nm channel spacing. The bit-error-rate (BER) measured against ...
Hybrid OCDMA/WDM system using complementary detection technique for FTTH access networks
(Institute of Electrical and Electronics Engineers (IEEE), 2011-09-25)
A hybrid optical code division multiple access (OCDMA) over wavelength division multiplexing (WDM) system is proposed for supporting large numbers of subscriber for fiber-to-the-home (FTTH) network. The system combines two ...
Development and performance evaluation of hierarchical quadrature amplitude modulation (HQAM) for image transmission over wireless channels
(Institute of Electrical and Electronics Engineers (IEEE), 2011-09-20)
Asymmetric modulation techniques like Quadrature Amplitude Modulation system is one of the key techniques in building a broadband mobile communication network because of increasing shortage of wireless communication channels. ...
Prolonging lifetime of wireless sensor networks with mobile base station using particle swarm optimization
(Institute of Electrical and Electronics Engineers (IEEE), 2011-04-19)
Wireless sensor networks are a family of networks in wireless communication system and have the potential to become significant subsystem of engineering applications. In view of the fact that the sensor nodes in wireless ...
New code for spectral-amplitude coding optical code-division multiple-access systems
(Institute of Electrical and Electronics Engineers (IEEE), 2011-06-16)
In this paper we present a novel code family for SAC-OCDMA system. The new code technique is called Dynamic Cyclic Shift (DCS) code. Which more flexible in selection the code length with variable cross correlation. ...
Performance evaluation of TCP Vegas versus different TCP variants in homogeneous and heterogeneous wired networks
(World Academy of Science, Engineering and Technology (WASET), 2011-02)
A study on the performance of TCP Vegas versus different TCP variants in homogeneous and heterogeneous wired networks are performed via simulation experiment using network simulator (ns-2). This performance evaluation ...
