Investigation of Jervol water types properties effects on underwater optical wireless OCDMA system performances for different modulation techniques

Abstract In this paper, an analytical evaluation of direct detection OCDMA system using zero cross correlation codes is presented in an underwater wireless optical channel (UWOC). Performances were evaluated by varying the main simulation parameters (range,transmitted power,number of users and inclination angle) considering different modulation techniques for different water types (categorized according to Jerlov classification).

AbstractThis study has presented the complete comparison non return to zero (NRZ) and return to zero (RZ) modulation techniques for upgrading long haul optical wireless communication systems. Electrical signal to noise ratio is measured. Q-ranges factor are measured at the receiver side for different transmission distance from 500 to 1000 km. As well as the performance parameters of optical wireless communication systems are estimated at different transmission data rates with possible maximum transmission distance. NRZ modulation technique has outlined better performance than RZ modulation technique for upgrading optical wireless communication systems.
