Abstract :
In this paper, we manufacture the parallel transmission system consisting of an infrared light emitting diode (LED), an avalanche photo diode (APD) module and a field programmable gate array (FPGA) board corresponding to 132, 540 logic elements (LEs) by way of trial, and evaluate the BER performance of the optical ZCZ-CDMA system with the equal gain combining (EGC) by the indoor experiment. As a result of indoor experiment with the parallel transmission system, BER performance improves with an increase in number of received APD by the EGC.
