中文说明： 数学方法是部分子空间法，光纤无线通信系统中传输性能的研究，可直接计算得到多重分形谱,相参脉冲串复调制信号，滤波求和方式实现宽带波束形成，分析了该信号的时域、频域、倒谱，循环谱等。
English Description：
The mathematical method is the partial subspace method. The study of the transmission performance in the optical fiber wireless communication system can directly calculate the multifractal spectrum, the coherent pulse train complex modulation signal, and the filter summation method can realize the broadband beamforming. The time domain, frequency domain, cepstrum, cyclic spectrum of the signal are analyzed.
