Due to power restriction of some laser sources, the use of same power (per bit duration) in optical codes in incoherent optical code-division multiple-access multimedia networks with variable quality-of-services was previously studied. In those studies, the performance of double-weight codes with the maximum cross-correlation function=1 was exactly analyzed, but an approximation was only applied to the codes with the maximum cross-correlation function>1 due to mathematical complexity. In this thesis, an exact analytical model of double-weight codes with an arbitrary maximum cross-correlation function is formulated and validated with computer simulation. This general, exact, and more accurate performance model is also useful for power-sensitive applications, such as in-service monitoring and fiber-fault surveillance in optical networks and sensor-identification in fiber-sensor systems using optical codes for address or user identification.
