Abstract :
For the first time, OFDMA and SC-FDMA (single-carrier frequency division multiple access) are compared experimentally as candidate uplink access techniques for next-generation PONs. Important issues like peak-to-average power ratio, optical beat interference, and symbol delay are studied and experimentally measured.
