摘要

本文提出了一种用时频表示(TFR)分析多速率线性系统中周期平稳信号的系统方法。我们利用阻塞操作的能力，以一种简单而有效的方式执行分析。我们举例说明TFR的强度进行这样的分析。其基本思想是-周期平稳信号的TFR与其阻塞版本的功率谱矩阵的行数直接相关。我们给出了包括非均匀滤波器组在内的示例，以突出分析的能力。

Cyclostationary signals in multirate linear systems

This paper presents a systematic approach to use time frequency representation (TFR) for the analysis of cyclostationary signals in multirate linear systems. We exploit the ability of blocking operation to perform the analysis in a simple yet efficient manner. We illustrate the strength of TFR for performing such analysis. The basic idea is — TFR of a cyclostationary signal is directly related to the rows of the power spectrum matrix of its blocked version. We present examples including nonuniform filter bank to highlight the capabilities of the analysis.
