The optimum transmit power for an incoherent optical code-division multiple-access (OCDMA) system is evaluated for various transmission distances and data rates considering the stimulated Raman scattering (SRS) nonlinear effects. Numerical simulations have been carried out for this purpose. It is shown that the optimum power decreases with the distance up to a certain distance where the optimum power...
A new detection scheme, namely AND subtraction technique is proposed and presented in this paper. The theory is being elaborated and the calculated and simulation results have been done by comparing AND subtraction technique against complementary subtraction technique by using DW code. In this paper we have proved that AND subtraction technique gives better bit error rate (BER) performance than complementary...
Double Weight (DW) code is presented here to support fiber-to-the-home (FTTH) access network in point-to-multipoint (P2MP) applications. This code with basic fixed weight of 2 possess ideal cross correlation properties, that are important characteristics in spectral encoding OCDMA system since these can eliminate multiple user interference and can reduce noise. The performance of DW code against Hadamard...
A new detection scheme, namely AND subtraction technique is proposed and presented in this paper. The theory is being elaborated and experimental results have been done by comparing double-weight (DW) code against the existing code, Hadamard. In this paper we have proved that AND subtraction technique gives better bit error rates (BER) performance than Complementary subtraction technique against the...

The subtraction detection techniques for a hybrid SCM spectral-amplitude-coding (SAC) OCDMA using double weight (DW) code family are investigated. The experimental simulation results show that the proposed new subtraction detection technique provides a better system performance.
