摘要： 本文提出用卷积法来简化受确定信号,特别是周期性信号调幅的已知频谱的随机信号的频谱计算.并在QPSK的周期性脉冲串上与传统的估值法作了比较.

Abstract: A convolutional algorithm is used to simplify the evaluation of the spectrum of a random process of known power spectral density and amplitude modulated by a deterministic signal, especially, by a periodic signal. The spectra of the periodic burst QPSK baseband signal are evaluated as an example, and the results are compared with those of the traditional algorithm.
