主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度

随机减量技术（Random Decrement Technique-RDT），其主要是利用样本平均的方法，去掉响应中的随机成分，而获得初始激励下的自由响应，(Random decrement technique (Random Decrement Technique-RDT), whose main method is to use the sample mean, remove the random component of the response, and the response to the initial excitation freedom of)
