使用高积累量实现多载波和单载波信号在高斯白噪声信道下的区分，并仿真了不同信道比下的识别率。程序用函数模块化编写，可以直接调用。-The distinction between multi- carrier and single- carrier signals in Gaussian white noise channel is realized by using high accumulation, and the recognition rate of different channel ratio is simulated. The program is modularly written and can be called directly.
