Multi-user, 10Gb/s spectrally phase coded O-CDMA system with hybrid chip and slot-level timing coordination

We demonstrate a multi-user, 10 Gb/s spectrally phase coded O-CDMA system with hybrid chip and slot-level timing coordination utilizing low power nonlinear processing. A new double Hadamard coding scheme is demonstrated to enable both chip-level timing coordination and full interference suppression without the need for synchronous detection.
