Free-Space Optical Communication Systems for Next Generation Networks
暫譯: 下一代網路的自由空間光通信系統

本書提供了自由空間光學（FSO）通信領域的見解，這被視為未來一代寬頻無線網絡的下一個前沿。作者討論了限制混合無線頻率/自由空間光學（RF/FSO）中繼技術實際應用的各種因素，以確定重要參數對混合RF/FSO中繼系統性能的影響。本書介紹了可以用來建模RF和FSO鏈路統計的各種通用通道模型。此外，還介紹了放大轉發（AF）和解碼轉發（DF）形式的合作中繼方案的建模。本書使讀者能夠理解在混合RF/FSO中繼中可以利用的各種減緩技術，以改善整體用戶體驗。作者討論了人工智慧和機器學習在無線光學通信系統領域的重要性。最後，探討了使用CNN和LSTM模型的光學無線通道建模，並研究了它們在提高通道估計的準確性和可靠性方面的潛力。
