Summary: 
We considered pulse width dependence in a time-spreading Optical Code Division Multiplexing (OCDM) system using a phase encoder and decoder (127-chip, time-spreading 800 ps) by simulation. It follows that in a fully asynchronous OCDM transmission, the light source pulse width had a 20 ps degree of freedom.
