We present the theoretical analysis and simulation of an encoder/decoder pair with applications in Optical Code Division Multiple Access (OCDMA) systems. The theory and simulations presented are valid for any technique that relies on the combination of dispersion/phase modulation/dispersion for spectral phase encoding. We perform a theoretical study of the system, characterizing its main limiting factors, and a comparative study of the Multi-Access Interference (MAI) and Bit Error Rate (BER) for a simple multi-user system at high-bit rate in a Passive Optical Network (PON) environment. The capacity of the system to carry out error-free operation for codes of different length and with different numbers of users is also demonstrated through simulation.
