A Novel Scheme for Seamless Integration of ROF System with OFDM-CPM WDM Passive Optical Network
Networks Fiber optics communications
2011/5/26
A novel scheme to generate, transmit and receive an optical OFDM-CPM signal in the architecture for seamless integration of ROF system with 4 × 2.5Gb/s WDM-PON is proposed and experimentally validated...
Comparison of OFDMA and SC-FDMA Channel Access Techniques in a Passive Optical Network Environment
Comparison OFDMA SC-FDMA Channel Access Techniques Passive Optical Network Environment
2011/5/25
For the first time, OFDMA and SC-FDMA are compared experimentally as candidate uplink access techniques for next-generation PONs. Important issues like peak-to-average power ratio, optical beat interf...
