Abstract

In this paper, a “diversity” on-off-keying (OOK) optical code-division multiple-access (O-CDMA) scheme is proposed and analyzed. The scheme transmits multiple copies of an optical code per data bit of one in order to improve code performance. Our results show that the diversity OOK O-CDMA scheme reduces error probability with little degradation on spectral efficiency, under the assumptions of similar code power and bandwidth expansion as the conventional OOK O-CDMA scheme. An important application of our diversity scheme, which solves the low code-cardinality problem of heavy-weight optical codes, is finally discussed.
