隨著通訊發展，資料傳輸量的需求與使用頻段也逐漸提升，目前有大量學者往更高可用頻段的兆赫波進行研究，但受到高頻無線通訊的物理特性影響，如果要達到與較低頻的無線通訊相同的訊號覆蓋範圍，需要架設的基地台數量也會增加，因此不會拘泥於有限的土地面積下，天空中的衛星就是一種有效解決訊號覆蓋率的方式，這也是Beyond 5G/6G 其中的關鍵發展技術之一。衛星的體積會限制內部的元件量，為了克服衛星雷射光通訊的傳輸通道損耗，必須使用光放大器來提高傳輸功率，然而直調雷射會將較高的傳輸能量集中在雷射載波上，進而導致訊號傳輸功率下降，使接收訊號的靈敏度降低。
本文的研究主題為透過雙二進位制編碼減少相同資料傳輸量所需的頻寬，並分析低軌道衛星至地面站所需的光功率，採用光載波抑制的調變技術提高接收端的訊號靈敏度，最後透過非線性補償訊號進一步提升傳輸效能。

With the advancement of communication technology, the demand for data transmission and the frequency of use have gradually increased. Currently, numerous researchers are exploring higher-frequency terahertz waves to address these demands. However, due to the physical characteristics of high-frequency wireless communication, increasing the number of base stations is necessary to achieve the same signal coverage as lower-frequency wireless communication. Therefore, to overcome the limitations of finite land areas, satellite-based solutions have become a key development technology in the realm of Beyond 5G/6G.
The size of satellites imposes limitations on the number of internal components. To mitigate transmission channel losses in satellite laser communication, optical amplifiers are employed to boost transmission power. Nevertheless, direct modulation lasers tend to concentrate higher transmission energy on the laser carrier, leading to a decrease in signal transmission power and a reduction in signal sensitivity at the receiver.
The focus of this research is to reduce the required bandwidth for the same data transmission volume through duobinary encoding. It also analyzes the optical power needed for low Earth orbit satellites to ground stations. Furthermore, it utilizes optical carrier suppression modulation techniques to enhance the signal sensitivity at the receiver end. Finally, non-linear compensation of signals is employed to further enhance transmission efficiency.
