Abstract: In this Paper, the comparative analysis of a fibre optics CDMA system with or without weighted code is presented using Matlab simulation. By changing various parameters of the systems, we compare two systems in terms of BER. As the number of active users increases the BER increases. It is found that the system using weighted code is better.
