Abstract
We proposed a hybrid OCDMA system, in which users are divided into 3 categories: frequency-hop (FH), time-spread (TS) and FH-TS codes´ users. Their address codes´ mathematical expression and codes´ cardinals are given separately. Their multi-access interferences as well as BER performances are also discussed. This system is very fit for the case that a small part of services are with high bit rate or high QoS, while great amount of services are common one.
