Abstract

A DOCDMA (dynamic optical code division multiple access) communication system is projected for high-bandwidth communication systems. At the receiver, a synchronized TOF with the same function is used as a decoder. In this system, an electrically controlled tunable optical filter (TOF) is used to encode the modulated broadband light source. This technique dynamically modulates the central wavelength of a TOF as per a functional code at the transmitter during the bit period earlier the transmission of the data. The system is examined taking into account multiple access interference (MAI), thermal noise, and phase-induced intensity noise (PIIN). In these paper we understand that the performance of proposed dynamic OCDMA. It’s improve the bit error rate & reduce the MAI (multiple access interference) & PIIN (Phase Induced Intensity Noise). The simulation result show that the proposed DOCDMA system reduces the PIIN effect on the performance of the system and improves the bit error rate (BER) performance at a maximum number of users. Also, it is found that when the effective power is large enough, the MAI becomes the main factor that limits system performance, whereas when the effective power is comparatively low, both thermal noise and PIIN develop the main restrictive factors with thermal noise having the main effect.
