Optical physical-layer network coding over fiber-wireless
Zhixin Liu, Lizhao You, Lu Lu, Soung-Chang Liew, Chun-Kit Chan · 2013
We propose and experimentally demonstrate the first optical physical-layer network coding (OPNC) prototype to boost throughput in an OFDM fiber-wireless network. Our technique does not require symbol-level synchronization and only requires moderate modifications of the packet preamble in IEEE 802.11 standard specification.
