摘要 | In this paper, we study and analyze the system performance of an optical code‐division multiplex access (CDMA) system implemented with synchronous receiver. In the traditional optical CDMA access system, optical signals emitted from users are transmitted at the same power level. When these signals arrive at the receiver terminal, due to different distances traveled for each signal from the transmitter to the receiver, they will be at different power levels. In this paper we propose a mechanism to estimate first the distance between a transmitter and a receiver and then from this distance information to estimate its associated time delay so as to shift the signal time frame structure and adjust its transmitting power level so that a synchronous receiving system is generated. Using the VPItransmissionMaker software the system performance of the proposed system is simulated, and the results show that the proposed synchronous receiving system gives better performance than a traditional synchronous transmitting system. |
