N2 - The Worldwide Interoperability for Microwave Access (WiMAX) presented in IEEE 802.16 has the aim to provide wireless broadband services to commercial fixed and mobile users. Free-space-optical (FSO) link can be utilized for establishing the connection between WiMAX base station and core network. This optical wireless technology is used for distributing WiMAX traffic because it represents a cost-effective solution, easy to be installed and supports high data rates. On the other hand, transmission of radio-frequency (RF) signals over a FSO link is strongly dependent on weather conditions. In our work, we study a mixed FSO/WiMAX link with primary aim to determine the overall error rate performance. Firstly, we provide a brief recapitulation of main results in this field. Secondly, we determine error rate dependence on different system and channel parameters. We observe the simultaneous effects of FSO and RF channel conditions on error rate performance. Further, we suggest some quasi cyclic low-density parity-check (LDPC) codes suitable for implementation in these systems and determine their error rate performance for different code words lengths.
