Abstract
In optical CDMA systems, many optical waves are simultaneously incident on each receiver photodiode. Since the photodiode also acts as a square-law detector to the optical fields, beat noise can occur in the passband of the receiver. We show that considerable amount of beat noise can occur in even a non-coherent system.
