摘要
Free space optical (FSO) communication link based on orthogonal frequency division multiplexing (OFDM) gives improved performance because of high bandwidth efficiency, improved robustness against fading, and narrow-band interference. Any FSO system requires line-of-sight (LoS) link and in non-LoS (NLoS) situation, the two users cannot communicate directly resulting in link outage. To solve this problem, this paper proposes to use relay-assisted NLoS-FSO link with energy-saving three time-slotted analog network-coding approach to make the successful communication with increased throughput and improved error performance. The error performance of laser link is evaluated in terms of receiver sensitivity. Gamma-Gamma distribution is used for atmospheric turbulence in this analysis. The performance of relay-assisted intensity modulated/direct detected-OFDM FSO link with and without analog network coding (ANC) is compared.
