Tools Used: OptSim
Data access security and ability to support asynchronous, bursty data transmission are two of the main driving forces behind a lot of interest in the OCDMA techniques. On the other hand, the poor spectral efficiency of OCDMA systems demand appropriate choice of coding techniques and multi-access interference (MAI) is often a limiting factor.
This example illustrates an OCDMA design in OptSim with a commonly used tree network topology layout as shown below:
