Abstract

Optical Wireless Communication (OWC) adopts laser beam as the carrier to deliver the message. It combines with the advantages of Microwave Communication and Fiber Optic Communication. The key technologies of OWC system includes source coding, channel coding, laser diode modulation, auto-alignment and channel. In this paper, the research progress on OWC in Xi'an University of Technology is introduced. The research on source coding involves in baseband modulation, frequency modulation, OFDM transmission and vertical layered space-time codes. The research on channel coding includes RS codes, Turbo codes, LDPC codes and so on. And the adaptive coding method is analyzed to meet the different channel characteristics. Propagation performance of laser is studied and bit error rate (BER) is measured under various weather conditions of rainy days, snowy days, foggy days, hazy days and so on. The experiment results show that applying channel coding methods can improve the system performance of OWC, especially under rainy, snowy, foggy weather conditions, the BER after decoding is up to 10^-6. Based on many years of research, the technologies of MIMO, OFDM and space-time coding are proved to be the key technologies that need to solve in OWC.
