2-D Wavelength-Time Optical CDMA System - Experiment and Simulation

In this work, we demonstrate 2D wavelength-time encoding and decoding OCDMA system. The 2D generalized multi-wavelength prime codewords are used for realization of communication system properties analysis. The encoders and correlators are designed and realized according to used codewords. The experimental data transmission is realized for 80 km optical link. The input and output pulse sequences of correlator are measured and analyzed for different number of active users. The auto-correlation and cross-correlation function and pulse sequences are simulated by PC soft and compared to measured pulse sequence.
