Some critical coding and modulation techniques in uav communication have been discussed in this thesis, including differential phase keying ( dpsk ), modulation multiple symbol detection ( msd ), adaptive trellis coded modulation ( atcm ), and space - time coding. this work was supported by the national defense 973 project. uav communication has many sophisticated technologies
本論文在國防973項目「無人機信息傳輸理論與方法研究」的資助下，結合現代數字通信領域的新技術，根據無人機通信的特點和需求，對其中的幾項關鍵技術做了深入研究。 -
The atcm solutions in many references are constructed by first choosing a specified code, such as coset code or multi dimension tcm, then change the information rate by adopting different modulation constellation collection and different way to divide the modulation constellation collection
已有文獻的自適應格形編碼調制通常是先確定編碼方案（如採用coset碼或多維格形編碼調制） ，通過採用不同的調制星座集合，和不同調制星座集合劃方式實現自適應。
