【摘要】 本文比较了时频分布中抑制交叉项（Ｃｒｏｓｓ一ｔｅｒｍｓ， ＣＴ）的方法和效果，提出了衡量时频分布的测度的必要性。Ｒｅｎｙｉ信息可作为信号复杂度的测度，本文进一步指出它还可作为时频分布的测度，并且可作为选择依赖于信号的时频分布参数的依据．更多还原

【Abstract】 The meeans and effects of interference attenuation in time-frequency distributions(TFDs) are compared, the necessity of a measure to estimate TFDs is proposed. Renyi information can be cd as the measure of signal complexity. This paper further suggests that it can ho be used as the measure of TFDs and the reference for selecting the signal-dependent parameters in TFDs.更多还原
