| Outline of Final Research Achievements |
In this research, I have proposed and manufactured the high speed and reliability optical wireless communication system considering receiver’s movement which is constructed by many infrared light emitting diodes (LEDs), avalanche photo diodes (APDs) and a field programmable gate array (FPGA) board corresponding to 132,540 logic elements (LEs) by way of trial, and it is obtained by combining of received signal and orthogonality of pseudo noise sequence. The bit-error rate (BER) performance of the proposed system is evaluated by the indoor experiment and computer simulation.
As a result, the system can reduce deterioration of BER performance even if the receiver moves, and the optimal distance between adjoined APD and APD exists.
