光无线通信（OWC）技术结合了光纤通信和无线电通信的优势,随着半导体激光器技术和光电探测器件的日益完善而重新兴起。光无线通信具有宽带大容量、安装快捷、机动灵活、低成本、无需频率申请等优点,具有广阔的应用前景。但光无线通信是以大气信道作为传输媒介,因此大气信道对光无线通信系统的影响较大。文章主要针对光无线通信系统中大气信道的干扰而采取的信道编码方案双模turbo码技术开展了深入的理论研究。
光無線通信（OWC）技術結閤瞭光纖通信和無線電通信的優勢,隨著半導體激光器技術和光電探測器件的日益完善而重新興起。光無線通信具有寬帶大容量、安裝快捷、機動靈活、低成本、無需頻率申請等優點,具有廣闊的應用前景。但光無線通信是以大氣信道作為傳輸媒介,因此大氣信道對光無線通信繫統的影響較大。文章主要針對光無線通信繫統中大氣信道的榦擾而採取的信道編碼方案雙模turbo碼技術開展瞭深入的理論研究。

Optical wireless communication（OWC） system bonds the advantage of fiber communication and radio communication,it springs up again along with the development of the progress of the semiconductor lasers and optoelectronic detectors.The main advantages of OWC system are that high bandwidth,large capacity,quick deployment,flexibility,low cost,license-free allocation,so it has widely promising application.However the OWC system＇s transmission medium is atmospheric channel,the atmospheric channel seriously impact the communication quality.In this dissertation,we focus on double modul turbo coded OWC system in order to eliminate atmospheric channel disturb.
