4th IEEE International Symposium on Electronic Design, Test and Applications (delta 2008)
xDSL Network Upgrade Employing FPGAs
January 23-January 25
ISBN: 978-0-7695-3110-6
This paper proposes an upgrade scenario for xDSL networks to provide broadband access for extended link lengths while demonstrating network grooming by means of more than one subscriber using a single network connection concurrently. This is achieved by applying Direct Spread Code Division Multiple Access (DS-CDMA) in a Fiber-to-the-Cabinet (FTTC) topology by means of a Field Programmable Gate Array (FPGA), used to demonstrate simultaneous user transmission and System-on-Chip (SoC) network element generation. Experimental results have displayed efficiency in ADSL link rates of 66% and 41% for back-to-back and 12 km-reach fiber links respectively.
