Multiple optical private networks over EPON using optical CDMA technique
FREE-DOWNLOAD M Gharaei, S Cordette, C Lepers… – Optical Fiber …, 2010 Ethernet Passive Optical Network (EPON) is an emerging low-cost technology which is an attractive solution for broadband access network [1]. EPON architecture is consisted of optical line terminal (OLT), star coupler (SC) and optical network units (ONUs) using tree topology. The
Performance of DS-CDMA downlink using transmitter preprocessing
Performance of DS-CDMA downlink using transmitter preprocessing and relay diversity over Nakagami-m fading channels FREE-DOWNLOADW Fang, LL Yang… – Wireless Communications, research Abstract—In this letter we propose and investigate a coop- erative downlink transmission scheme for direct-sequence code- division multiple-access (DS-CDMA) systems, in order to achieve relay diversity. Transmitter zero-forcing (TZF)-based preprocess- ing is employed […]
Blind adaptive multiuser detection for the MC-CDMA
Blind adaptive multiuser detection for the MC-CDMA systems using orthogonalized subspace tracking FREE-DOWNLOAD I Ali, DN Kim… – ETRI journal, 2009 – In this paper, we study the performance of subspace- based multiuser detection techniques for multicarrier code-division multiple access (MC-CDMA) systems. We propose an improvement in the PASTd algorithm by cascading it with the […]
