Abstract :
We compared the bit-error-rate (BER) and throughput performance of coherent time-spreading (TS) optical code division multiple access (OCDMA) systems with PPM and OOK signaling. The results indicate that PPM-OCDMA with an appropriate pulse position multiplicity performs better than OOK-OCDMA in the receivers´ bandwidth limitation case.
