Abstract:
Based on wireless optical communication characteristics and wireless access techniques, the Media Access Control (MAC) protocol in wireless optical code division multiple access network is presented and studied. In the analysis, background noise, multi-access interference, Avalanche Photo Diode (APD) noise, and thermal noise are taken into account. With Optical Orthogonal Code (OOC), the mathematic model of network throughput is derived and evaluated according to numerical results. Simulation results indicate this MAC protocol can obtain high network throughput. Furthermore, with shorter packet length or longer code length, a better network throughput is obtained.
