- 面向高动态场景的新载波体制AFDM：（二）基本原理
AFDM的子载波则是由Chirp组成，每一个子载波在时频域上并不交叠，保持正交性，并可以看到在时频域上AFDM各个子载波频率随时间线性变化。 利用DAFT进行数字实现，同样可以观察到AFDM各个子载波在频域上的周期延拓现象。

- 面向高动态场景的新载波体制AFDM：（一）基本情况
AFDM全称Affine Frequency Division Multiplexing，仿射频分复用，AFDM体制脱胎于基于Chirp的多载波波形。 AFDM于2021年在IEEE ICC Workshops 上由Ali Bemani等人提出，核心思想是将信息符号调制在 Chirp信号 上，根据信道特征进行调整来达到接近最优的传输性能，其调制解调
