Quantize and Encode Relaying Through FSO and Hybrid FSO/RF Links
IEEE Transactions on Vehicular Technology, 2015 A relaying scheme that uses both radio frequency (RF) and free space optical (FSO) links is investigated. In the proposed quantize and encode relaying (QER), a mobile source broadcasts the RF signal using quadrature amplitude modulation (QAM). The relay estimates and quantizes the log-likelihood ratio (LLR) of each received bit in the symbol and ...
