Analysis of Turbo Codes over Hybrid Optical/RF Channels

An analysis on the bit error rate performance of turbo codes for hybrid optical/RF channels is presented using the transfer function bounding technique. The optical channel includes the effects of atmospheric turbulence, which is represented using the gamma-gamma model. The effects of various turbulence conditions on the performance of the hybrid link is investigated. The role of the RF link in the hybrid channel is analyzed using the trade-offs between the RF and the optical signal-to-noise ratios.
