Abstract :
An optical orthogonal code division multiple access system (OOCDMA), was introduced for the case of no avalanche photodiode (APD) noise and no thermal noise. Extensions of this work are presented, including the effects of APD and thermal noise as well as interference for the OOCDMA direct-detection receiver with an APD. In addition, the hard-limiter role before the receiver correlator in the presence of thermal and APD noise is also examined
