It is shown that the horizontal and vertical factorial moments are equivalent only when they are used in combination with the cumulant variables
發現:在一般情況下,只有在引入累積變量后,縱向階乘矩才與橫向階乘矩相等。Therefore, in the study nonlinear phenomena in high energy collisions the hfm can be used only in combination with the cumulant variables
因此,在高能碰撞非線性現象(間歇和分形)的研究中,只有採用了累積變量時,才能使用橫向階乘矩進行計算。In the aspect of blind - identification, the mutual power spectrumx time - frequency distribution product of two delay signals are used as the features of classification. the cluster analysis and cumulant invariants of mpsk signals are used to automatically classify communication signals
在信號識別中,選取信號的互功率譜、時頻分佈、 mpsk信號的延遲相乘信號作為分類特徵,利用模式識別中的聚類分析以及mpsk信號的基於高階累積量構成的分類特徵不變量實現了信號調制類型的自動分類。For the issue of blind parameter estimation of dsss / bpsk signal damaged by strong additive white gaussian noise ( awgn ), this dissertation mainly researches on carrier doubler method ( cdm ), auto - correlation method ( acm ), delay - and - multiply ( dm ) method and fourth - order cumulant 2 - d slice method
針對受強高斯噪聲污染的dsss / bpsk信號對抗技術中的盲參數估計問題,本文著重研究了平方倍頻法、時域自相關法、延遲相乘法三種常規的單參數估計法以及四階累積量2 - d切片多參數估計法。分享友人
